Underwire bras are famous for giving women the best lift, support, and shape. However, they’re not always known for being the most comfortable type of bra—especially for women who wear a larger cup size.
If you haven’t found an underwire bra that you can wear all day, a poor fit is often the culprit. But other issues such as straps, fabric, and design can also be uncomfortable.
However, underwire bras can be comfortable, especially when they’re exceptionally made with high-quality fabrics and attention to detail.
To help you find the most comfortable underwire bra you’ve ever worn, we’ve compiled a guide to selecting the best bra.
Keep reading to learn how you should shop for an underwire bra, and our top picks for comfort and quality!
Why Wear Underwire Bras?
Underwire bras are popular for several reasons, but your bra must be properly fitted to guarantee that the underwire properly contours your breast tissues—from under your arms to where your cleavage is.
Once you’ve found the correct fit, the right underwire bra will take your breasts to the next level. You’ll experience support, shape, and lift that you didn’t know existed!
Underwire bras are designed to contour the natural shape of our breasts. They bring the weight of your breasts closer to the front, while also lifting them upwards and the right bra will encapsulate your entire bra tissues, which raises your breasts and creates a round shape.
Most women today typically seek a natural-looking, uplifted silhouette. Underwire helps accomplish this coveted look and with a properly fitted underwire bra, you will experience the utmost support. However, how much support depends on the type of bra you wear.
Underwire is the rigid semicircle that is sewn into the band of a bra. It is typically made of plastic, resin, metal, or steel.
Because they’re designed to follow the curve of the breast root, underwires range in shape and size. You’ll choose from three underwire shapes, depending on your needs: J-shaped, plunge/rocker, and U-shaped.
J-shaped underwires are the most popular as they are found in most everyday bras, from demi bras to balconettes. They’re popular because they’re suited for a variety of breast root shapes. The lower center can accommodate touching—or close-set—breasts.
If your breasts don’t require much support, you may like a plunge/rocker wire. These banana-shaped, shorter wires are comfortable for those with high-set breasts or short torsos, as plunge/rocker wires are typically used in plunge and push-up bras.
U-shaped wires are longer and used most often in strapless bras, or those not reliant on shoulder straps for support.
You’ll also find u-shaped wires in bras made for breasts larger than a D cup size, since they’re not as wide or plunging as J-shaped underwires, they best fit women with narrow breast roots.
How to Shop for a Comfortable Underwire Bra
Eight out of 10 women are wearing the wrong size bra.
Before shopping for a new bra, it’s essential to get professionally fitted by an expert who is familiar with all bra styles and how they fit.
And don’t stay stuck on one size, as all brands and styles have different standards. You could wear two or three sizes, depending on the bra materials and manufacturing. Continue to try on different sizes until you find the one that’s perfect for you.
If you find that a particular bra fits perfectly in the band, but is too small or big in the cup size (or vice versa), try that bra’s sister size. Sister sizes are either one size up or down from your typical size. If you find that one breast is bigger than the other, round up.
If you go up in band size, you’ll move down in cup size. For example, if you typically wear a 34B, a 32C or 36A would be your sister size.
As you shop, try not to skip a bra because it’s more expensive. A perfectly-fitting, top-quality bra is worth it if it will give you the comfort and lift you need.
From flattering everyday bras to sexy push-up options, we’ve made a list of our favorite options. Each of these Cosabella bras is made with pride and care in Italy.
