Ehhh, I guess they are medium. They're definitely not large. It depend how I move, but mostly when I'm doing a lot of moving causes my straps to slip down.
I'm not sure if having the right bra size is the only way to prevent this. I think kind of bra it is,plays a whole. I've been measured, even measured myself , and I get the bra according to that size. Sometimes some bras sizes run differently. Like I can buy two separate bras from Rue 21, one will fit great and the other one not so much. Also how new or old (worn out) the bra is.1
