Frequently asked questions
What size should I buy for an oversized look?
We recommend going up one size from your baby's current size for a true oversized fit. Alternatively, choose a set that's already designed to be roomy, which often has sizing that accommodates growth.
Are oversized baby outfits safe for sleep?
Yes, but ensure they fit snugly around the neck, arms, and legs to prevent any loose fabric. Avoid sets with drawstrings or accessories. For sleep, a well-fitted footed pajama is still the safest choice.
How do I style an oversized baby outfit?
Balance the volume with snug accessories like a fitted beanie or a pair of soft booties. For a fashion look, roll up the sleeves and pant legs for a confident, put-together aesthetic.
Can oversized clothes hinder crawling or walking?
Not when chosen correctly. Look for sets with ribbed cuffs and elasticated hems to keep fabric out of the way. The best oversized cuts are designed to allow full range of motion.
