Floral square neck dress

This piece was an online order from a trendy store. I tried it on and it was too big for me so I left it in its bag to take it to a seamstress. I never got around to it so I figured someone else can get better use out of this super cute dress. I noticed there is some small stains on the inner armpit. I don’t know how they got there since I didn’t wear it out. I think they could come out if I tried to gently wash it. I will do so on request.
