An unlined bra gives you real support and a natural shape without the bulk of foam or padding. The 24/7® Second Skin Unlined Bra uses double-layer microfiber cups to smooth your silhouette and still let your true shape show through. It feels like a lighter version of you, with everyday coverage from morning through night.
Wear it every day under T-shirts and fitted knits, layered at the office, or from your morning commute into the night.
Thirdlove offers over 60 bra sizes from 32 to 44 band and bra cup sizes from AA to H cup, including our exclusive half cup sizes. Using your current bra size as a starting point, you can refer to the bra cup size chart below to refine your fit.
When using the chart to find your bra size, keep in mind:
Measure snugly around your rib cage (underbust) and around the fullest part of your bust, in inches. Step 1 gives your band. For step 2, subtract your underbust from your bust and find the difference in your band's column. These are the sizes our Bra Size Calculator gives.

An unlined bra supports and shapes you without foam or padding, so your natural shape shows through instead of being reshaped by a molded cup. On the 24/7® Second Skin Unlined, double-layer microfiber cups add a smooth, seamless finish while keeping the profile light. If you want everyday coverage that feels close to bare, this is the trade-off working in your favor.
Yes, this style has an underwire, and support comes from that wire plus the band and straps rather than from padding. The band does most of the lifting, so a well-fitted band is what keeps you supported all day. If you prefer a wireless feel, Thirdlove also makes wireless unlined styles in the same collection.
No, the double-layer microfiber cups give you light opacity and a smoothing look, so the bra covers you without heavy padding. Because there's no foam, you'll see your natural shape, but the fabric itself isn't sheer. In nude tones like taupe, it also stays low-profile under light-colored clothing.
An unlined bra has no foam or padding, so it follows your natural shape. A lined or padded bra adds a molded layer that shapes and can add volume. Unlined styles feel lighter and closer to bare, and support still comes from the band, straps, and underwire. Choose unlined when you want a smooth, natural look under clothes rather than added projection.
Yes. It comes in bands 32–44 and cups A–H, including half cups, so it's built for a wide range of fuller busts. The underwire and supportive band do the lifting without padding, which keeps a larger bust comfortable and smooth. If you're not sure of your size, take Find My Fit or chat with a live fit stylist for a recommendation.
Start with Find My Fit,, which walks you through a few questions and returns a size to try. Because this style includes half cups and bands 32–44 with cups A–H, you can often dial in a more exact fit than a standard run allows. You can also chat with a live fit stylist if you're between sizes or switching from another brand.
Hand wash it and lay it flat or hang it to dry to protect the microfiber cups and elastic. The nylon and spandex blend keeps its stretch and smooth finish when you skip the dryer. Gentle washing also helps the underwire and band hold their shape over time.
You get free exchanges for 60 days, so you can size up or down if the fit isn't right. Orders of $75 and up qualify for free shipping and rewards when you join the free rewards program. At $74, adding a small item or a second pair can push you over that threshold.
