The square neckline and matching shell borders are the two measurements that make this sage-green outfit recognizable. This crochet toddler summer set pattern uses DK yarn, a 4 mm hook and intermediate garment skills to produce a tank top, drawstring shorts and five-petal appliqué. The reference dimensions follow a toddler-scale project, while the separate construction makes length and waist adjustments possible before final assembly.
The Design: What Makes This Summer Set Different
Three structural decisions define the photographed set. First, the tank uses a nearly square upper edge with relatively wide straps instead of a halter neck; that spreads the garment weight across the shoulders and keeps the neckline geometry visible. Second, the shorts use a contained waistband plus crochet drawstring rather than relying on decorative ties alone. Third, the same fan-shaped border appears on both garments, so the crochet toddler tank top pattern and crochet toddler shorts pattern read as one set.
The common mistake is enlarging the shell border without recalculating its repeat. That causes the hem to flare even when the body gauge is correct. Here, the body circumference is settled first. Decorative shells come last, using an evenly divisible edge count.

Invisible decrease is not required for this garment because shaping is handled through stitch distribution rather than amigurumi-style decreases.
Gauge and Sizing
Make a washed and dried swatch before starting the garment.
Aim for approximately:
19 sts = 10 cm in the main fabric
A 60-stitch panel then measures roughly 31.5 cm wide. Two panels give approximately 63 cm around the body before seam behavior and blocking are considered.
If 60 stitches measure 34 cm instead, the finished top will be about 68 cm around. Change the stitch count before working the full piece.
Pattern — Step by Step
This is an original garment pattern derived from the visible design in the reference image.
Tank Front
Yarn: sage green
Chapter 62.
Row 1: Dc in 3rd ch from hook and in each ch across. (60)
Row 2: Ch 2, turn. Dc in each st across. (60)
Rows 3–6: Repeat Row 2. (60)
Row 7: Ch 2, turn. Dc in first 2 sts, ch 1, sk 1, dc in next 2 sts across, adjusting the final repeat with dc as needed to retain 60 working positions.
Row 8: Ch 2, turn. Work dc in each dc and 1 dc in each ch-1 sp. (60)
Rows 9–24: Repeat Rows 7–8 eight more times. (60)
Measure from lower body edge to underarm. Target about 17–19 cm before adding the decorative hem.
Rows 25–28: Ch 2, turn. DC in each st. (60)
Fasten off. Leave a 25 cm tail for side seaming.
Tank Back
Yarn: sage green
Repeat the Tank Front through Row 28.
Do not add shoulder straps directly to the back.
Fasten off with a 25 cm side-seam tail.
The two equal rectangles create the straight horizontal neckline visible in the photograph rather than a curved armhole.
Left Strap
Yarn: sage green
Chapter 9.
Row 1: Sc in 2nd ch from hook and across. (8)
Rows 2–18: Ch 1, turn. Sc in each st. (8)
Check the strap against the intended wearer or a well-fitting tank.
Fasten off. Leave 25 cm for sewing.
Right Strap
Repeat the Left Strap. (8 sts × 18 rows)
Before stitching either strap permanently, pin both pieces about 3–4 cm in from the side edges of the front and back. The two placements should mirror each other.
Tank Lower Scallop Border
Yarn: sage green
Join yarn at one side seam after the top is assembled.
Round 1: Ch 1, sc evenly around lower edge. Adjust spacing so the final stitch count is a multiple of 6. Join with sl st.
Round 2: Sk 2 sts, 5 dc in next st, sk 2 sts, sl st in next st. Rep around.
Fasten off.
This six-stitch repeat produces the fan edge visible along the tank.
If the shells cup inward, the base edge contains too few stitches. If they ripple heavily, it contains too many.
Waistband Shorts
Yarn: sage green
Chapter 11.
Row 1: Sc in 2nd ch from hook and across. (10)
Row 2: Ch 1, turn. Sc BLO across. (10)
Rows 3–96: Repeat Row 2. (10)
The ribbed strip should sit at the intended waist without being pulled hard.
Bring Row 96 to the foundation edge.
Sl st the short ends together through both layers.
Do not fasten off.
Shorts Upper Body
Rotate the waistband so its long edge faces upward.
Round 1: Ch 1. Work 96 sc evenly around the waistband edge. Join with sl st. (96)
Round 2: Ch 2. Dc in each st around. Join. (96)
Round 3: Ch 2. Dc in next 3 sts, ch 1, sk 1 around. Join. (96 working positions)
Round 4: Ch 2. Dc in each dc and 1 dc in each ch-1 sp. Join. (96)
Rounds 5–14: Repeat Rounds 3–4 five times. (96)
Place markers at stitches 1, 25, 49 and 73. These quarter points help keep the crotch division centered.
First Shorts Leg
Count 48 stitches for the first leg section.
Join the leg opening at the crotch point.
Round 1: Ch 2, dc evenly around the 48-st section. Join. (48)
Round 2: Ch 2, dc around. (48)
Round 3: Ch 2, dc in next 3 sts, ch 1, sk 1 around. Join. (48 working positions)
Round 4: Ch 2, dc in each dc and ch-1 sp. (48)
Round 5: Ch 1, sc around. (48)
Fasten off.
Second Leg Shorts
Repeat First Shorts Leg exactly. (48)
Lay the shorts flat with the waistband centered. Both leg openings should finish at the same row level before edging is added.
Scalloped Leg Border Shorts — Make 2
Join sage yarn at the inner leg.
Round 1: Ch 1, sc around, adjusting only if needed so the count is divisible by 6.
Round 2: Sk 2, 5 dc in next st, sk 2, sl st in next st. Rep around.
Fasten off.
Repeat on the other leg.
Drawstring
Yarn: sage green
Ch approximately 95–105 cm, or roughly twice the finished waist plus 10–15 cm for tying.
Beginning in the second chain from the hook, sl st into every ch.
Fasten off.
Thread the cord through evenly spaced gaps near the waistband. Position both ends at center front.
Do not use the drawstring as the sole method for making an oversized waist fit a much smaller child.
Five-Petal Flower Applique
Yarn: darker sage center and cream petals
Target finished diameter: 4–5 cm.
With darker sage:
Round 1: Make MR, 10 sc in ring. Join with sl st. (10)
Change to cream.
Petal 1: Ch 2, 3 dc in same st, ch 2, sl st in next st.
Repeat the petal sequence around, using two center stitches per petal to form 5 petals.
After the fifth petal, sl st to the first attachment point.
Fasten off. Leave 25 cm tail for sewing.
The flower sits on the wearer's upper-right chest rather than in the center.
Assembly
Place the tank front and back with right sides together. Match the lower corners and underarm edges first.
Seam each side from the lower body edge to the top edge using mattress stitch or controlled whip stitch.
Turn the tank right side out and confirm the finished circumference before adding the straps permanently.
Pin the first strap 3–4 cm inward from the left side edge at front and back. Sew through several horizontal stitch bars rather than one row only.
Repeat with the second strap, matching its front and back placement to the first within 3 mm.
Add the tank scallop border after side seams are complete so the shells continue around the garment without a visual break.
Close any remaining crotch gap on the shorts with the same yarn, keeping the seam flat and centered between the legs.
Add both shorts shell borders, then thread the drawstring through the waistband openings from center front.
Pin the five-petal flower to the wearer's upper-right front and stitch around the center plus each petal base.
Weave each yarn tail through at least 4–5 cm of neighboring stitches, change direction once, trim, then block the set to the measured dimensions.
The completed piece consists of one square-neck tank, two straps, one pair of drawnstring shorts, three matching scalloped edges and one five-petal flower.
7 Technical Tips
Lost edge stitches: Place a marker in the first and last stitch of every tank row. Losing one stitch on only six rows removes more than 3 cm from the combined circumference at a 19-stitch-per-10-cm gauge.
Incorrect fabric density: If a 10 cm swatch is more than two stitches tighter than the 19-st reference, the garment will finish materially smaller. Change hook size before starting the full 60-stitch panel.
Unequal straps: Measure both straps after Row 18 and keep their finished lengths within 3 mm of each other. A longer strap on one side rotates the square neckline.
Flower placement drift: Pin the appliqué before sewing and keep its outer edge at least 15 mm away from the strap seam. Moving it too close to the strap makes the upper front look crowded.
Scallop flare: Test one six-stitch shell repeat before completing an entire hem. A border that forms waves while lying flat has too many base stitches for the fabric tension.
Shorts twisting: Mark the upper body at four equal 24-stitch quarters before dividing the legs. A crotch split that is even four or five stitches off-center can make one leg hang forward.
Loose tail weaving: Run garment tails through at least 4–5 cm of similar-color stitches, then reverse direction once. A short straight tail can migrate out after washing, especially in smooth cotton.
Fit Adjustments
The photo cannot reveal the child's exact measurements, so age labels should be secondary to circumference.
For a wider top, add stitches to both front and back equally. At a gauge close to 19 stitches per 10 cm, adding two stitches to each panel adds roughly 2.1 cm to the total circumference.
For extra length, add matching two-row mesh repeats before Rows 25–28. Do not lengthen only the solid upper section because that changes the visible proportion between open fabric and square neckline.
For longer shorts, repeat Rounds 3–4 on each leg before the final single-crochet setup round.
The waistband requires the most caution. Measure the intended wearer's waist, compare it with the relaxed ribbed strip, and adjust the number of ribbing rows before joining.
Why DK Cotton Fits This Design
The uploaded set shows crisp stitch openings and defined shell fans rather than a fuzzy halo. DK cotton or a cotton-rich blend is therefore a closer structural match than bulky acrylic or chenille.
DK or 8-ply yarn also works well with hooks around 4 mm for lightweight child garments.
Fiber choice changes the finished result. Mercerized cotton tends to produce sharper shells. A softer cotton-acrylic blend can make the main fabric more elastic.
Swatch first and use the measured stitch width, not the yarn label, to decide the final starting count.
Reproducing the Photograph More Closely
The green sample in the image is not a granny-square set. Its design depends on repeated linear stitchwork, a restrained two-color flower and three coordinated shell borders.
Use wisely as the only body color. Reserve cream for the petals and a darker green for the center. That keeps the appliqué distinct without changing the monochrome structure of the garments.
The flower should stay small. A 4-5 cm pattern matches the proportional scale visible in the photograph. A much larger application would occupy too much of the tank front and change the design.
Strap width matters too. Eight single hooks create a broad strap instead of a thin cord. This helps preserve the square-neck appearance.

Conclusion
Block the tank and shorts to measured dimensions before judging strap position or hem flare. The next practical step is to make a 10 cm DK swatch with the 4 mm hook, record its stitch count, then recalculate the 60-stitch panels if your gauge differs from the reference. Save this crochet toddler summer set pattern to Pinterest and share the finished set on Instagram with #SageDaisySummerSet. Photograph the garment flat beside a ruler so later size changes can be compared accurately. For this specific design, would you keep the five-petal flower on the upper-right chest as photographed, or repeat a smaller flower on one shorts leg?
