    Super comfy bra

    This bra is the one I’ve been looking for. I’m either a 34DD and 36D depending on the brand, so I purchased a L+. This bra gives me a little lift while still being soft and smoothing. Love the no underwire. Bra washes well. My only concern is that I’m starting out on the middle hook instead of the loosest, but it’s a minor issue. I’m hoping it doesn’t stretch out too quickly.

    Great Investment!

    Fit is perfect, fabric feels very comfortable, colors are lovely. I hand wash and the bras look as though brand new even after a few years of wear.

    Good, not my favorite Thirdlove

    I've had a few different Thirdlove bras now and overall I would say this is a solid one. I think for my breast shape some of the other styles are better but this is still good quality and a nice baby blue color.

    Holds the girls great, but fabric irritating

    This bra is simply wonderful, just like most things you find here in the online store. Unfortunately, there is something in the fabric at the seams that irritates my skin, leaving me with a red and uncomfortable rash which takes days to go away. Alas, I cannot use any bra, but the 24/7 Classic T-Shirt Bra.

    the support pieces in the sides took me a bit to get used to, but beyond that, i have no complaints. the fabric is soft and luxurious feeling, but the design doesn’t compromise function.

I love these bras. I

"I love these bras. I got them in about 6 colors. However, I just realized that I’ve been wearing the wrong size. At 30F I should be wearing the XS ++ the problem with the XS++ is that the straps are thicker and I like the shape of the S+ better. So despite having the band ride up in the back and having to adjust the cups so I don’t spill out, I make the S+ work. Wish these just came in actually bra sizes."

— Regina L. (4/5)

Perfect fit

"I love this bra. I have tried so many bras and have a very hard time finding a comfortable fit, but this one fits really well and os really comfortable."

— Ashley P. (5/5)

This bra is great for long trips!

"I recent made 2 very long international flights and wore this bra, It was great because it didn’t dig in and was like wearing a looser jog bra."

— Helen D. (5/5)

So comfy!

"Such a comfortable bra with good coverage and support. I got it in the blue color "lake" and it is such a cute color"

24/7 Classic Wireless Bra

"I am Registered Nurse and am always moving and rushing from one place to the next. The place where I work does not have central air or air conditioning except for the residents if they have their own private air conditioner. This summer was was wicked hot and where I live in Maine, the summers are very humid. When summer lands in the great north, it hits hard lol! This bra has been so supportive and overall extremely functional when it comes to comfort. I don’t even notice I have a bra on and it’s extremely soft! Moisture has also reduced greatly in that area and it is by far the best bra I have owned! ThirdLove is my new love for sure!"
