Go raid your stash right now. I mean it. That pretty mint yarn you have been saving for something special? This is the project. And that soft pink skein sitting next to it? Grab that too.
This baby dress set combines some seriously satisfying techniques. You will work a fitted bodice in single crochet, then transition into a gorgeous fan shell stitch for the skirt that creates that dreamy, lacy texture. The peter pan collar adds vintage charm. The matching booties and headband bow complete the set beautifully. Fair warning: this is an intermediate level project. But if you are comfortable with basic stitches and ready to stretch your skills, you can absolutely do this.
The construction is clever. You work the dress top down in one piece, which means minimal seaming. The collar gets made separately and attached, giving you that crisp layered look. And those little unicorn buttons at the waistband? Pure sweetness.
Why This Baby Dress Set Works So Well
This pattern creates a complete layette set that looks far more complicated than it actually is. The fitted pink bodice features a scalloped mint peter pan collar and sweet cap sleeves. The full flared skirt uses a shell fan stitch pattern that shows off beautifully in the mint yarn. A gold satin ribbon threads through eyelets at the waist, accented with unicorn novelty buttons for that whimsical touch.
The matching pieces tie everything together. Mint booties with gold satin bows coordinate perfectly with the dress. A pink crocheted headband features a large bow embellishment that frames any baby face adorably.
This set fits newborn to 3 month sizes, with the pattern including detailed notes for sizing up through 12 months.
Materials You Will Need
Before you begin, gather everything so you can work uninterrupted.
Yarn:
Hook: US size E-4 / 3.5 mm crochet hook
Notions:
Yarn suggestions that work beautifully:
Paintbox Yarns Simply DK gives excellent stitch definition that shows off the fan shell texture. It is machine washable and comes in perfect shades of bubblegum pink and mint green. You will need 2 skeins of pink and 2 skeins of mint.
Lion Brand Pound of Love works as a budget option, though you should swatch carefully since it runs slightly thicker.
Scheepjes Catona in mercerized cotton creates a dressier, stiffer drape that holds the collar and skirt shape without blocking.
Gauge (Please Do Not Skip This)
18 stitches and 20 rows = 4 inches in single crochet worked flat using Color A and your E-4 hook.
For the fan shell skirt: 1 fan shell repeat (6 stitches) = approximately 1.33 inches wide. 2 rows of fan pattern = approximately 1 inch tall.
I know gauge swatches feel tedious. But this is a garment. A difference of even one stitch per inch will significantly alter how this dress fits. Work a swatch at least 5 inches square, wash and dry it the way you would wash the finished dress, then measure. Your future self will thank you.

Special Stitches You Will Learn
Fan Shell Stitch
This creates the gorgeous lacy texture throughout the skirt. Each fan consists of 5 double crochets worked into a single stitch, flanked by single crochets that anchor the fans. Here is how it works:
Row 1 (setup, RS): Sc in first st. Sk 2 sts, 5 dc in next st, sk 2 sts, sc in next st. Rep from * to end.
Row 2 (WS): Ch 3, turn. 2 dc in first sc. Sc in center dc of fan, 5 dc in next sc. Rep to last fan. Sc in center dc of last fan. 3 dc in last sc.
Row 3 (RS): Ch 1, turn. Sc in first dc. Sk 2 sts, 5 dc in next sc, sk 2 sts, sc in center dc of fan. Rep to end, placing final sc in top of tch.
Rows 2 and 3 form the pattern. Once you get the rhythm, it flows naturally.
Scallop Edging
This decorative border appears at the collar, sleeve cuffs, and skirt hem:
Sl st in next st, sk 1 st, 5 dc in next st, sk 1 st. Rep around or across.
