Your bra band should fit snug against your back and not feel loose.

Ideally, you should always be able to hook your bra on the center hook. If it feels loose when it's fastened at the center hook, try a smaller band size. The band should rest just below your shoulder blades. Can you slip 2 fingers between the band and the side of your rib cage with no more than 1" of stretch? Then your band width is fab.

The swell of your bust should
flow smoothly into your bra
cups without looking like it's
spilling over.

You need a larger cup size or you need to wear a bra that offers more cup coverage. (For example, switching from a demi style to a full coverage style.)

You should never have to suffer with digging or painful straps.

Always make sure you can slip a finger between your shoulder and your bra strap. If you can't, loosen those straps a bit.

The bottom of the front panel of your bra should always rest flush against your chest.

If your bra is gaping, it means the cups are too small for you. Try a cup size larger.

When one of your cups puckers or wrinkles, you probably have
an uneven bust (which is quite common).

Bras made with foam cups or microfiber/stretch fabric will balance your size difference to perfection.

Falling bra straps are more than just annoying. You could be wearing the wrong size or the wrong style.

Without regular checkups, your straps may need a little fine tuning, or they may have just lost some elasticity. Tighten those straps on a regular basis. (You may even want to try a racerback style to see if that helps.)

If the underwire in your bra is poking you or digging in, it's time to check a couple of things.

Increase your cup size or try a bra with more cup coverage. Also, make sure the band and straps are snug enough to give you the support you need.

When both cups wrinkle and pucker, it indicates a less-than-perfect fit.

See if going down one cup size smooths things out. If not, feel free to ask one of our expert Fit Stylists for help.
