Our pick
Cake Lingerie Cotton Candy
No other seamless bra we tested accommodates breast size fluctuation with the support and comfort of the Cotton Candy, making it ideal as a first postpartum nursing bra.
Buying Options
*At the time of publishing, the price was $54.
Of all of the seamless bras we tested, none felt as supportive and comfortable as the Cake Lingerie Cotton Candy. The soft bra’s higher than usual spandex content makes it incredibly resistant to stretching out—even when you sleep in it. The top of the bra sits higher than most, accommodating engorgement in the first few weeks of nursing and keeping you from spilling out then and later on. In the world of seamless bras—which are among the most comfortable but least structured options—designs are so basic that women with larger busts suffer. The Cotton Candy has built-in features like a full back and knit panels in the shape of underwire, making this a supportive option for the entire size range of this bra—S to XL, spanning 32B to 42F.
Our pick
Hotmilk Forever Yours
The Hotmilk Forever Yours has flexible underwire that does a better job of keeping moms free of clogged ducts and mastitis than typical underwire bras. Plus, it looks good under a T-shirt.
Buying Options
*At the time of publishing, the price was $26.
Of all the bras we tested, none gave us better shape under a T-shirt than the Hotmilk Forever Yours. Its design is clean and simple, with just enough padding to hide nipples, flexible underwire that supports and lifts while also adjusting to size fluctuations, one of the most adjustable bands among all the bras we looked at, and cotton lining the interior of the cups, adding breathability and softness. The Forever Yours comes in sizes 32A to 38F.
Our pick
Hotmilk Show Off
Among the wireless nursing bras we tested, the Hotmilk Show Off provided the greatest lift and support, and our testers unanimously liked the way they felt and looked in it as well.
Buying Options
*At the time of publishing, the price was $50.
With its highly effective construction, the Hotmilk Show Off outperformed all the other wireless models we looked at in terms of support and lift, and bested a few underwire bras as well. It has one of the widest size ranges available in a structured nursing bra and feels so unrestrictive that a few of our testers even slept in it comfortably. Design features like the breathable cotton lining, higher coverage A-frame, and streamlined lace detailing helped make it a favorite of our testers, who all genuinely like the way the bra makes them look and feel, which is not true of any other bra we tested. Available in sizes 28B to 46I.
Our pick
Kindred Bravely French Terry Racerback
Unlike many of the sleep bras we tested, the Kindred Bravely keeps it simple: This inexpensive bra is soft, supportive, and comfortable without any unnecessary engineering.
Buying Options
*At the time of publishing, the price was $0.
Many of the nine sleep bras we tested have too much going on—body mapping, hook-and-eye attachments, lace trim, liner fabrics—which made us appreciate the Kindred Bravely French Terry Racerback for prioritizing softness, support, convenience, and not much else. This bra is easy to pull aside for middle-of-the-night feedings, yet has enough stretch and tautness to retain nursing pads without trouble and keep you from spilling out when you’re not nursing. It feels more like a second skin than any other bra we tried. Available in 28B to 42G.
Runner-up
Bravado Designs Body Silk
A true-to-size fit makes this comfortable, supporting bra an easy one to order online
Buying Options
*At the time of publishing, the price was $50.
The design of the Bravado Designs Body Silk is clean, its nylon-spandex fabric is stretchy yet supportive, and the bra comes in one of the widest color ranges we’ve seen. Most important, its sizing chart is accurate, unlike those of some other brands, making this bra easy to order online. But although we love the sporty V-neck shape, we think most people will feel more secure wearing the higher neckline of our main seamless pick. We also found that the Bravado’s sling strap offers far less support while nursing than our main pick’s more substantial triangle-shaped sling. Available in S to XL, accommodating 32B to 42F.
Also great
Paramour Lorraine
This budget underwire bra has a smooth shape, soft cups, and unique features like optional front closure and a lacy racerback.
Yes, the Paramour Lorraine includes lacy detailing, but its racerback design also provides serious support, and was the feature our testers loved about this inexpensive bra. The two closure options (front and back) make it easier to get on and off and more adjustable than most front-closure-only bras. Though the unique strap adjustment design—a ladder of rungs onto which the hook slides—is difficult to adjust one-handed, it effectively keeps the straps from loosening throughout the day. Unlike our main underwire pick, this bra goes all the way from 36D to 42G.
