Lovely Mermaid Baby Girls Princess Adventure Bathing Suit Halter Bikini Sets Swimsuit Swimwear Fancy Dress Costume

Would this still be cute for a 1st birthday party even if it wasn’t a pool party?

Does this run true to size? My daughter just turned one and the sizes that are available are only 6-12m & 3t-4t

I have a soon to be a year old babygirl. She is 28lbs and wears size 3t. Do i need to get that size for this moana costume as well or smaller?

My daughter is 14 lbs - would 6-12 months fit her okay?
