This is a complete three-piece baby set. You get a bubble romper with bunny applique, a matching hat with floppy ears, and booties with tiny bunny faces. The whole thing uses single crochet. If you can work basic stitches in rows and rounds, you can make this.

The romper construction is straightforward. You work two flat panels, seam them together, then add the bib and straps. The hat starts with a ribbed brim and works upward in continuous rounds. Booties begin at the sole and build up.
I would call this an intermediate project. Not because the stitches are hard, but because you are managing multiple pieces and assembling them into a cohesive garment. Take it one section at a time and you will be fine.
Why This Bunny Baby Romper Set Works So Well
The blush pink color photographs beautifully for newborn sessions. The texture from all that single crochet creates a dense, structured fabric that holds its shape wash after wash. And those bunny ears on the hat? They flop just right.
This crochet pattern produces a romper set sized for newborn to 3 months or 3 to 6 months. Instructions are written for the smaller size with the larger size adjustments in parentheses throughout. One pattern, two size options.
The construction method keeps things manageable. Instead of working the romper in one complicated piece, you make a front panel and a back panel separately. Then you seam them at the sides and add the finishing details. Breaking it into smaller pieces makes the whole project less overwhelming.
Materials You Will Need
Yarn: Worsted weight yarn in blush pink as your main color. You need approximately 200 to 250 yards total. Small amounts of white and light gray for the appliques. A tiny bit of dusty rose for the bootie cuffs if you want contrast.
Hook: US size G-6 / 4.0 mm crochet hook

Yarn Suggestions That Work Great
Lion Brand Vanna’s Choice in Dusty Rose, White, and Silver Gray works perfectly. It is machine washable, easy to find, and gives excellent stitch definition.
Paintbox Yarns Simply DK held double brings a DK weight up to worsted gauge. The blush and ivory shades in this line are gorgeous.
Cascade 220 Superwash in a soft pink gives a more premium feel with beautiful drape. It is machine washable on gentle.
Any worsted weight yarn (weight category 4) that meets gauge will work. For baby items, stick with machine washable fibers. Avoid fuzzy or novelty yarns because you need clean stitch definition for the ribbing and applique details.
Gauge Information
Getting gauge right matters for fit. This is a garment, not a blanket.
18 single crochet stitches and 22 rows equals 4 inches / 10 cm when working flat.
18 single crochet stitches and 18 rounds equals 4 inches / 10 cm when working in the round.
To check your gauge, chain 24. Work single crochet in rows for 26 rows. Block lightly and measure the center 4 by 4 inch area. If your swatch is too big, go down a hook size. Too small, go up a hook size.

Abbreviations and Stitch Definitions
blo means back loop only. Instead of inserting your hook under both loops of the stitch, you go under only the back loop. This creates a stretchy ribbed texture.
ch means chain. Wrap yarn over hook, pull through the loop on your hook.
sc means single crochet. Insert hook into stitch, yarn over, pull up a loop (2 loops on hook), yarn over, pull through both loops.
sc2tog means single crochet two together. This is your decrease stitch. Insert hook into next stitch, yarn over, pull up a loop. Insert hook into the following stitch, yarn over, pull up a loop. You now have 3 loops on your hook. Yarn over and pull through all 3 loops. You just turned 2 stitches into 1.
inc means increase. Work 2 single crochet stitches into the same stitch.
sl st means slip stitch. Insert hook, yarn over, pull through both the stitch and the loop on your hook in one motion.
RS means right side. The front of your work.
WS means wrong side. The back of your work.
MC is your main color, the blush pink.
CC1 is contrast color 1, white.
CC2 is contrast color 2, light gray.
CC3 is contrast color 3, dusty rose.
Pattern Notes Before You Start
The turning chain (chain 1 at the start of each row) does NOT count as a stitch. When the pattern says 32 stitches, you should have 32 actual single crochet stitches, not 31 plus a chain.
When working in rows, chain 1 and turn at the beginning of each row.
The romper front and back are worked separately, then seamed. The bib is worked directly from the top of the front panel.
Keep track of your right side and wrong side. The ribbing looks different on each side.

Check buttons and seams before each use. Inspect regularly for loose threads.

Time to Complete
Plan for 12 to 18 hours total. The romper body takes 6 to 8 hours. The hat needs 2 to 3 hours. Booties take another 2 to 3 hours. Appliques and finishing add 1 to 2 hours.
Work in sessions. Maybe tackle one piece per day over a week. This crochet tutorial breaks into natural stopping points.
