Bra Types and Their Benefits

Many women use bras to provide support and shape. However, there are many other types of bras that can provide the same benefits if not more.

Strapless bras: The strapless bra in particular is a great option for women in the summertime since it provides support without any straps to get in the way. It also helps to prevent sagging and busting when you’re at the beach, poolside, or working out during the day.

Bandeau bras: The bandeau bra is a great alternative for women who like their breasts pushed up and supported. It is especially good for those with smaller cup sizes who don’t want anything supporting their breasts from underneath them.

Push-up: These bras lift and separate your breasts, giving them a lifted and youthful appearance. These bras usually have a thin underwire that is sewn into the cups to provide shape. They often come with removable padding, which can be replaced as needed.

Balconette: This type of bra provides volume as it lifts the breasts as well as gives them a lifted appearance by pushing them together. Its shape is like that of a triangle, which gives your breasts an uplifted look. Push-up bras may also provide more support than it does. Its design might be attractive to some people, but it has less support overall.

Why Fit Matters Most When Buying a Bra?

Fit matters most in a bra when you are looking for support. If you are not sure what size to buy, try measuring your shoulders, underbust, underarm, and bust.

Many women opt for what they think is the right size based on their breast size. However, this may not be the best option especially if you are looking for support in a bra.

When buying bras or trying on bras in-store or online it's important to know what type of bras fits best so that you can find the perfect one for your needs.

How to Avoid Common Bra Missteps

There are a few mistakes that women often make when choosing bras that are worth addressing;

  1. The band of the bra should always be flush against your back. Otherwise, you will not get the support that you need.
  2. Women should never skip out on getting professionally fitted for their bras. A lot of stores have trained staff who can help you find the perfect size and style to suit your needs.
  3. It is important to know what your breast type is in order to get the right bra for your shape.
  4. Do Know Your Breasts: It's important to know what kind of bras you need based on your breasts and body type. If your breasts are soft and firm, if they're small or large, there is a bra out there that will work for you! Being an informed shopper is a key part of shopping. It's important to research different brands and styles before going into a store so that when you do go into a store, you can make the most out of your time while not spending too much money.
