Great Yoga/summer Tank Top/crop Top

Buffy The Vampire Fans? I bought this while binge watching the show 😂 Does anyone know the episode she wore a shirt super similar?

It’s light cotton, better for smaller boobs as there isn’t any padding it’s just t-shirt material but surprisingly not see through at least on me...the back is completely open with string crossing through. It’s is very secure so if you have tied it properly you shouldn’t have a Janet moment.

I would say xs size but it depends how much skin you want to expose...it says L because it was bought from an Asian sizing store. 65% cotton ( very soft)
