Major problem -- Simmons loves those tanks that are super low-cut on the sides.
Women's tanks are high-cut on the sides (small armholes), if your upper arms/ shoulders have any size to them at all the bottom will be right there in your armpit.
Oooh, here's the actual "Sweatin' to the Oldies" look!
If you don't have enough chest hair, you gotta glue some on.
And make sure those shorts are
tiny.
I'm thinking you might have better luck at a thrift store/ resale shop -- it's all just so so 80's.
