It is said that a cell phone should not be stored in a bra or have prolonged skin to phone contact. I get an unusual image at to what happens when your phone in your bra rings. Do you reach in and retrieve the phone or turn and do that privately?
Money is FILTHY and I would not want that in my bra or have to pull it out and hand it to someone after being in my bra.
I cannot imagine how a set of keys could be at all comfortable to be elasticized by my bra up against my breast. Then, to be in a public parking lot, fishing through my shirt, only to pull out my keys for anyone to see me seemingly groping myself.
My ear buds have two wires attached to the buds. I would hate to have that tangled up in my bra or make it look like I had two misplaced nipples peeking through my shirt.
So, to put keys, money, a phone and earbuds in my cleavage would leave no room for my actual cleavage. My bra is the size of my breasts, not the size of a fanny pack and then some.
If you do not want to carry a purse, you can try some nice small cross body enlarged wallet size purses that you do not have to carry.
