I am selling a butterfly stretchy cowgirl dress

This is my old sister dress. She only wear it one time I washed it thoroughly and it’s like a white shirt up under it, but you cannot take it off. The brand is from RM LA and the size is a small size 10 in kids and it’s super cute has buttons going down and you can tie it and it’s really very stretchy on the way so you can fit it and it’s gonna be perfect fit.
