Free Unicorn Baby Dolls Onesie Crochet Pattern

Unicorn baby doll onesie description

This free unicorn baby dolls onesie crochet pattern is an easy crochet dolls clothes project for 14″ baby dolls.

Continuing with my collection of crochet dolls clothes, I couldn’t resist making a unicorn-themed onesie. I love unicorns, they really are so pretty. And honestly, what could be cuter than a baby dressed as a unicorn?!

The crochet dolls onesies have gone down a storm with my children and they love dressing up their babies ready to take to bed. You can also check out my free kids unicorn onesie crochet pattern to make a matching set.

The Unicorn dolls onesie is designed to fit 14″ baby dolls. The hooded dolls onesie buttons up the front. The hood is decorated with a unicorn horn, ears, mane, and pretty flowers. Overall, the dolls clothes are super cute and colorful and will put a smile on any child’s face!

How to crochet a unicorn onesie for a doll

The Unicorn baby dolls onesie crochet pattern is easy skill level. The dolls outfit is mainly made using half double crochet but you will need to know all your basic crochet stitches to complete the pattern.

The onesie is made in one piece and the only sewing involved is to attach the decorations to the hood.

To make the dolls onesie I used DK (weight 3) yarn. I used a 4mm crochet hook. Please check your gauge before starting and adjust your hook if you need too. This will ensure that the clothes fit your doll. The crochet dolls clothes pattern uses approximately 98g (277m/307yd) of yarn. You will also need 2 buttons to complete the pattern.
