What is an Unlined Bra?

Shopping for a new bra online? It could be tricky if you’re unfamiliar with key bra features and the distinctions between them. For example, what is an unlined bra and how does it vary from any other? We’ll help you determine the difference across a range of bra types so you can take the guesswork (and indecision) out of your intimates search.

What does “Unlined” Bra Mean?

Unlined bras are typically crafted from a single panel of cloth without any backing or padding to reinforce the cups. This super-light construction translates to bras that are often sheer and contoured to follow the natural curve of the breasts. You’ll want to wear an unlined bra when a barely-there underpinning is in order — but keep in mind that less coverage also means less modesty. If that’s a concern, stick to unlined bras only under thicker knits and layered tops.

Most Common Types of Unlined Bras

Unlined Bralette

Offering easy-wearing comfort together with just-enough support, bralettes are one of the most popular types of unlined bras. Some are smooth and contouring like True Body bralette styles with optional light padding, while others are designed with pretty flourishes, like lacy backs, that look chic under sheer or loose tops. Though unlined bralettes are usually wireless, they can still provide excellent hold for larger-chested women: longline versions designed with wide, reinforced underbands are the way to go.

Unlined Demi Bra

Unlined demi bras are romantic silhouettes that offer minimal coverage to give breasts a natural-looking boost. Women with slope-shaped breasts (density concentrated toward the bottom) will benefit most from this style, while those with more fullness on top may experience unintended spillover. Because unlined demis tend to be translucent, modesty and show-through can also be a concern. A partially lined version will solve this — look for bras that are skimpy along the upper edge and opaque just beneath: a perfect demi-cup compromise.
