what is a triangle bra

Triangle bras are more than just a passing lingerie trend. They’re a classic lingerie style that we reach for again and again.

One of our favorite lingerie styles, triangle bras are much more common than you’d think. Their sexy, minimal coverage design can be found in bikini tops and bralettes in fabrics such as sheer mesh and stretch lace. Their soft padded cups often feature removable padded inserts so you can customize the level of coverage. Plus, they have endless styling options and they’re perfect for layering under a sheer top or slouchy tank.

With their plunging neckline, barely there coverage, and sexy design, this popular style can be found in many bralettes. In fact, you may already have a triangle bra in your lingerie wardrobe!

Wondering what’s so great about triangle bras and if they’ll work for your bust? Read on for everything you need to know.

What is a triangle bra?

A triangle bra gets its name from its triangle-shaped cups. Unlike the half moon cups of a demi bra, triangle bras are designed to provide less coverage – making them a sexy alternative to padded wireless bras. They have an versatile plunging neckline that works under a number of low-cut tops. Plus, many triangle bras are wireless and comfortable enough to wear all day long.

Are triangle bras only for small cup sizes?

No! Triangle bras provide lightweight support and shaping for both small and large busts.

For people with full busts (DD to K), look for triangle bras that have seamed cups, thick straps, a wide band, and a hook and eye closure in back for the most supportive fit. Keep in mind that a triangle bra won’t provide the same support as your favorite t-shirt bra or underwire bra, but what they lack in support they make up in style.

Will a triangle bra give my bust a natural look or a more rounded shape?

Triangle bras are designed to enhance the natural shape of your bust. Their design is closer to that of a bralette than a t-shirt bra.

For a rounded shape, look for a demi bra, t-shirt bra, or padded bra. In most cases, you’ll need a bra with molded cups to get the rounded shape you’re looking for.

Fit tips

When shopping for a triangle bra, keep in mind that the level of support they provide varies depending on their construction.

A triangle bra with a thin band will provide less support than a triangle bra with a wide band – this is because at least 80% of a bra’s support comes from the band. A bra with a wide band with boning is a more supportive option than one without.

Depending on the brand, triangle bras can be found in sizes like L and XL and band/cup sizes too. If you have a full bust, opt for a triangle bra that has cups with underwire in your bra size for the best fit.

Where to buy triangle bras

Your local lingerie store is one of the best places to shop for triangle bras. Specialty lingerie stores stock a wide range of sizes and styles, so you’re sure to find one you like. Plus, you’ll be able to try on the style before you buying – which is great if you’ve trying triangle bras for the first time.

In addition to local lingerie boutiques, you can find triangle bras online, too. Check out popular stores like Nordstrom, Neiman Marcus, Kohl’s, Nordstrom Rack, and Macy’s for the best selection in sizes from XS to 4XL and A-DD+ cup sizes.

Final considerations

Triangle bras are a beautiful, comfortable lingerie style that can be worn year round. They’re perfect for the hot summer months when you just want a lightweight bra. In soft fabrics like modal and microfiber, they’re a comfortable option for sleeping or lounging at home, too.
