/fa/ - Fashion

Hey /fa/, I'm coming to you because I am a pleb. Wife is searching for a racerback tank with split vents (?) like the one pictured. The image at left is Under Armour's "Sapphire" tank, which is NOT what she's looking for - she is looking for one she saw at the gym, which comes together almost in a wrapped back, but with two diagonal 'tails' on the vent, like the tails on a fancy tux?

Anyway: /fa/, help me find the tank my wife is looking for. Who makes such a thing? Can you recommend search terms? I've tried tanks, racerbacks, vents, wrap look, etc. and come up with nothing. Help!
