ThirdLove’s strongest documented strength is fit. Its bras come in exclusive half-cup sizes, and loyal buyers are enthusiastic. One wrote, “Great bras, the best. So comfortable and worth the cost,” another said “I’ve gotten 5 bras now from them and love them so much!” and a third said “The feature to pick your size was very accurate.” ThirdLove is a San Francisco-based intimates brand known for its 24/7 bra collection, wireless bras, bralettes, sports bras, underwear and loungewear. What sets it apart is its sizing system. ThirdLove says it created the first bra in half-cup sizes, offers styles from AA to H cups (with bands generally 32 to 44), and uses an online Fit Finder quiz to recommend a size.
The flagship 24/7 Classic T-Shirt Bra costs about $72 and shows more than 61,000 on-site reviews. It has ultra-thin memory foam cups, is made of 76% nylon and 24% spandex, and comes in half-cup sizes. The 24/7 Classic Wireless Bra costs about $68, and other popular styles include the 24/7 Classic Uplift Plunge, Second Skin Unlined Bra, minimizers and sports bras. ThirdLove offers a 60-day fit guarantee with free exchanges for eligible orders, a rewards program (Hooked Rewards), frequent sales, and Fit Stylists who help with sizing.
The honest caveat: ThirdLove’s Trustpilot score is 3.9 from 166 reviews, but 37% of all reviews are one-star. Recent complaints focus on service friction rather than the bras. One buyer said, “I am having a hard time getting past the AI bot,” and another warned that “each returned order charges a $4.99 processing fee.”

We analyzed ThirdLove’s Trustpilot profile (166 reviews, a 3.9 TrustScore, 38% five-star and 37% one-star, with a 100% reply rate to negative reviews), plus ThirdLove’s official product pages, sizing information and fit guarantee terms. Note that ThirdLove hasn’t invited Trustpilot reviews recently. GlossGirly has no commercial relationship with ThirdLove that affects this verdict. Comfort note: a well-fitted bra shouldn’t dig in, cause pain or leave deep marks. If you have persistent shoulder, neck or back pain, see a clinician rather than relying on a bra alone.
ThirdLove’s sizing is its defining feature. Beyond standard cups, it offers half-cup sizes (for example, 34C½), which help people who fall between sizes or have slightly different-sized breasts. Styles range from AA to H cups, and bands generally run from 32 to 44. The online Fit Finder quiz recommends a size in a couple of minutes, and many buyers say it was accurate. Several longtime customers have worn ThirdLove for years and say the fit is why they return. Not everyone finds their perfect fit. One buyer said bras didn’t seem to fit smaller busts unless the band was very narrow, and some buyers order neighboring sizes to compare. Use the 60-day fit guarantee to exchange freely if the first size isn’t right.
Buyers consistently praise comfort and quality. The 24/7 Classic T-Shirt Bra uses ultra-thin memory foam cups for shape without bulk and pleated straps designed not to dig in. Reviewers call the fabric comfortable and say bras hold up over time. The range covers T-shirt, plunge, wireless, unlined, minimizer, lace and sports styles, plus underwear and loungewear. One first-time buyer said her minimizer bra impressed her enough to plan more orders. For people who wear a bra every day, ThirdLove’s comfort and fit can justify the premium price.
ThirdLove’s human support team gets strong praise. Reviewers describe Fit Stylists who retroactively applied missed discounts, honored flash-sale prices, reshipped orders sent to the wrong address, replaced a damaged bra and re-checked sizing, and gave unexpected credits. The weak point is the front-line AI chat agent. Several buyers say it was hard to reach a person, and one only got connected after expressing frustration. ThirdLove says the AI agent needs an email address and order number before forwarding you to a Fit Stylist. Have those ready to speed things up. ThirdLove replies publicly to every negative Trustpilot review, usually within a week.
ThirdLove’s 60-day fit guarantee includes free exchanges for eligible U.S. orders, but returns can carry a processing fee. One buyer said she was charged $4.99 for each returned order, even when shipping several together, though ThirdLove says it refunded unused label fees in her case. Final-sale items can’t be returned or exchanged, and orders placed through third parties, such as a TV shopping deal, follow different rules. Several buyers also say discount codes disappear when editing the cart, or that the app processed an order unexpectedly. Our advice is to choose exchanges over refunds when possible, keep tags on, apply discount codes at the final step, and buy directly from ThirdLove.
ThirdLove’s bestseller has ultra-thin memory foam cups, a smooth finish under clothing and half-cup sizes. It shows more than 61,000 on-site reviews. It’s best for everyday wear under T-shirts and fitted tops. Use the Fit Finder quiz, and try the half size if you usually fall between cups.

An unlined bra praised by reviewers for its softness and true-to-size fit. It’s best for a natural shape and lightweight comfort. Unlined bras show less shaping, so it suits people who prefer minimal structure.
A minimizer style designed to reduce projection under clothing. One first-time buyer said she really liked hers after a Fit Stylist helped confirm her size. It’s best for fuller busts wanting a streamlined look. Contact a Fit Stylist if you’re unsure of your size.
“Thirdlove has a customer for life!” — Johanna Meier, Trustpilot reviewer (US, 5 stars, Customer service credit)
“The purchase and return experience was easy” — Dawn, Trustpilot reviewer (US, 5 stars, ThirdLove order)
“Don’t seem to fit smaller bust unless you are very thin band width” — suramom, Trustpilot reviewer (US, 5 stars, Bras)
“Trying to return it (and I am still trying) has been a nightmare.” — Janice Z., Trustpilot reviewer (US, 1 star, Bra return)
“I like the products very much, but the purchase process is highly flawed.” — Lisa T, Trustpilot reviewer (US, 3 stars, ThirdLove order)
ThirdLove is worth it for people who struggle to find a good fit, especially those between cup sizes, and want comfortable everyday bras with excellent human support. Use the Fit Finder, prefer exchanges over refunds, buy directly, and have your order details ready for the AI chat. If budget is your priority, there are cheaper options, but few match ThirdLove’s half-size range.

ThirdLove remains one of the best brands for bra fit. Half-cup sizes, a wide AA-to-H range, an accurate Fit Finder and comfortable, well-made bras explain why loyal customers keep coming back, and its human Fit Stylists earn genuine praise.
The trade-offs are an AI chat that can frustrate, return processing fees, checkout and discount-code glitches, and different rules for third-party orders. Buy directly, use exchanges rather than refunds, and keep your order details handy. For anyone tired of bras that almost fit, ThirdLove is a strong recommendation.
