Welcome to Bra Anatomy 101 with the help of my friends at Warners, one of the most accessible, effortless, everyday bra companies. 

You might be thinking “I know the parts of a bra. I’ve been wearing one since I was a kid!” But the truth is, most folks (even those that have been wearing bras for MANY years) don’t know these basics about bra parts and how they should fit. What’s the point in learning the parts of the bra? Education is power! I’ve been fitting and teaching folks about bras since 2005 (that’s 18 years and thousands of chests at this point) and knowing the basics is key to feeling comfortable and confident every day. We just weren’t taught a lot about bras, even though most of us put one on every morning! 

So, let’s learn together! Below is a jumpstart guide to the different parts of a bra, along with some of my best fit tips, and a few favorite bras from Warners so you can see this advice in action. Hurray!

Psst! The brand linked here is a proud partner of mine (so grateful to share them with you!). I always share items that I truly love and can help you say hurray!

Bra Anatomy 101

Part 1: The Band. The band of the bra is responsible for 90% of the bras support, ya’ll. Pro tip: make sure this is wide and soft for a secure but cozy fit. It should fit snug like a hug! And ideally, the band should be adjustable for a custom fit. In fact, the Easy Does It® Wireless Lift Convertible Comfort Bra (RN0131A) has 4 hooks and eyes for ultimate adjustability!

Part 2: The Cups. Cups can be lined which is great for modesty, coverage, and shape. Or they can be unlined like the Signature Support Underwire Unlined Full-Coverage Bra (35002A) which is more flexible and fuller coverage. This kind of style is great for separating the bust and avoids puckering with button down shirts!

Part 3: The Underwire. Underwires offer a frame for the bra, and should tack against the front of the body right between the bust, across from the back band. This equals a great fit!

Keep in mind that bras are like shoes, and a poor fit will mean discomfort, but a great fit will equal support and comfort. An underwire bra in the right size and fit for your body will actually feel really great! Plus, some underwire bras like the one seen here even have built-in cushions around the underwire for a cozy feel. Welcome all of your bust inside that wire and let the wire rest on your body, not on your bust.

And if you do want to go wireless, your bra should still fit everything inside where the wire WOULD be, and rest against your front torso securely.

Part 4: The Straps. These offer just 10% of the support and their main job is to keep the bra cup flush against your body. A stretchy strap should only reach about 1” off your shoulder when adjusted properly. Tip: a wide cushioned strap is extra comfortable, and be on the lookout for convertible straps which work great under racerback tops!
