Super cute! No size tag but will fit a small medium. Ifs very similar to the Nala bodysuit, just sleeveless. Believe this is a sample. Can’t seem to find anything that is similar. Let me know if you have any questions. Crotch area is adjustable. One button string should be a tightened a tiny bit. Color is a gorgeous green with sort of yellow or chartreuse color. It’s really cute. Materials from Nala bodysuit 63% Rayon, 34% Nylon, 3% Spandex
