Pour two to cheap lingerie three capfuls of baby shampoo -- or use the recommended amount of a detergent formulated for delicates, if you prefer -- into your washer. Use the gentlest and shortest cycle available on your machine.
After the cycle is done, remove the bras from the bra bag, unhook them, and lay them flat to dry. Laying them on top of the dryer on a towel while a load is drying, may help them dry sooner.
Find the proper cup size. Unlike other bra styles, a T-shirt bra's cups must provide maximum coverage around the sides and over the tops of the breasts. Too little coverage creates seam bulges and other bumps, which defeats the purpose of the smooth-seamed T-shirt bra.
Test the band size. Turn sideways in the fitting room mirror. The front of the band must rest at the same level as the back. If the back is higher, the band is too large. Also check if you can slide two fingers under the band. If it's too snug, the band is too small.
Measure around your rib cage. Start by placing the end of the measuring tape in the middle of your chest. Run the measuring tape below each breast and around your back. Write down this measurement.
Take a measurement of the width of your breast you want your bra to cover. Do this by taking a measurement across your breast. Make sure the tape is touching your body exactly where you would want the widest part of the bra to touch.
Choose the style that's right for you. Underwire bras come in several different varieties, so you need to find one that suits your style and clothing choices. If you wear many low-cut tops, you want a bra that won't show, so a full-coverage cup would be a bad choice. If you're large-chested, you might opt for something with more coverage, since you need more support.
Pick comfortable straps. The perfect underwire bra should have straps that feel comfortable after a long day. They shouldn't dig into your skin or bunch up. Some models now have wide straps and gel cushions to make your bra even more comfortable.
