This is an Athleta Diamond Fastest Track Tank Top in a size medium. The colors are black and gray. The inside of the sides has grippy material, and there’s cinching toward the middle of the top. It’s in very good used condition as pictured. It’s so flattering and cute on! Sadly it doesn’t fit me, I’m actually looking to buy another size because I love this top so much. I love bundles and offers, feel free to make one! Bundle any 3 items marked 3 for $6 and either send an offer or I will :)
