This tank is fab! Versatile, so soft and comfortable, cool layered design. Bought along with the matching Podium Leggings and they are both *chef’s kiss*. Could sleep in them! The tank does not have a built-in shelf bra, so there was concern that my usual P.E sports bra size of XS might be too big, as items described as “tanks” I usually do XXS (for reference I’m 5’8”, 32B chest). But ordered the XS and it fits perfect with or without something additional underneath, so I’d say it’s TTS for sports bra sizing! I’ve worn it for pilates, and under overalls and a blazer. New favorite for sure!
