LB: Marks are okay as long as it doesn't hurt. You should put a bra on and say, "Oh, this feels a little tight." It's when it's, "Oh, I can't breath" that it's not okay. If the bra's not snug, it can't hold up your breasts, and you're always going to have saggy breasts in a loose bra. Always.

Some women will say, "I'm not comfortable in this." Well, why even wear a bra? They'd be comfortable if they didn't wear a bra at all! You’ll be more comfortable in a bra that fits any day of the week over a bra that doesn’t.

RB: Is there a rule of thumb for where the tightening clasp on the strap should be?

LB: If you have to tighten it all the way down to the bottom of the strap, near the beaus of the band, it's the wrong kind of bra for you.

RB: What should women with large chests be aware of?

LB: Most are trying to get support from the bra straps, and that’s a real no-no. Never, ever try to get support from the straps. You should get your support form the band, not from the straps. When you tighten your straps and they dig into your shoulders, it can cause nerve damage and can give you headaches. And, besides, you’ll fall out the bottom eventually.

RB: Is it true that you're not supposed to wear the same bra two days in a row?

LB: You should always rotate your bras! How you store them is also important. For instance, if you buy t-shirt bras, you never want to bend one cup into the other. You always want to lay it flat and lay one top of the other and kind of keep a rotation going. You put the one you just wore in the back keep the new one to wear in the front.

RB: So no cup into cup?
