Only wored once for just try on. It says 6-9 months but fits for 12 months as well. I guess long dress for 6-9 months, midi dress for 12 months. I was going to put this on my daughter's 1/2 birthday but we didn't celebrate 1/2 birthday at the end. And tried on for a year old birthday, which was so beautiful but I already had first birthday looks... so that was it. Pretty dress. ----- Your offers and bundles are always so welcome! ----- I am selling multiple place, so if item is sold out on another platform, list might disappear.
