It's a good thing my cat loves playing with these, or I would truly be out of $10.00+. These are the WORST. They take a long time to adjust because your bra straps always twist around. That is almost as uncomfortablt as how tight your bra gets when it's pulled so tightly, especially under your cups. Loosening the straps doesn't really help. You're MUCH better off buying racerback bras, or using a tiny rubberband instead.
