Easter Gem! Vintage dress New XS adorable yellow

This adorable vintage dress is truly an awesome find . It’s new with tags. The size in the dress says simply Large but it is NOT a woman’s large , it appears to fit a small women or older child possibly a 16 or so zipper on the side. I wore a 2/4 and I’m larger breasted and it was too small for me. Hits above the knee colors are yellow and white . Easter gem!
