So soft and adorable! Just as pictured.
The most perfect gift. Fits great. Soft ribbed material. Pattern is beautiful!
The romper is adorable, but the one in the picture had ruffles on the butt, and the one I received in the mail does not have ruffles on the butt. That was very disappointing especially for the price.
I’m giving as a gift! Love the fabric. So soft. It’s a baby present for a new dad who loves to hunt.
