Cute chicken print romper

Yumi (British brand) romper with cap sleeves and a drawstring to cinch waist. Not sure what the material is but definitely something synthetic, feels like a rough silk. The size is marked 2/4 but I'm definitely a 4/6 and this fits great. Very flex. There are light, basically imperceptible, stains by the armpit (it has been professionally dry cleaned). Tried to capture the stain in the 4th pic. Price has been marked down accordingly. This is the only flaw and it's basically brand new otherwise.
