    Best Bra Ever!

    I have tried so many bras trying to find one that fit and was comfortable. This was it! I now have 4 and couldn’t be happier. I forget I’m wearing a bar half the time and somehow every shirt fits and looks better!

    Excellent

    Overall very happy with this, stays up and is somewhat comfy (as comfy as strapless bras can be). Only 4 stars because of comfort. Very happy that I finally found a go-to bra for summer!

    Total convert!

    I tried this bra on a whim, even sizing up from my usual size at my usual store. Soooooo comfy. I realized soon that I completely stopped wearing my other bras, and only reached for this. And I'd get annoyed when it was in the wash! So, I solved my own problem and bought more.

    Great bra!

    Love that it can quickly switch to racer back - its brilliant. And super comfy.

    Comfortable all day!

    I didn’t read the description well enough and was surprised when I received the bra and it had a little bit of a push up/padding. That’s not my preferred (I have two of The Base bras and love them), and I think I could’ve sized up as a result for a more correct fit, but the bra is super comfortable and could not be seen under a t-shirt. I recently wore for the first time, all day walking around, etc., and forgot I was wearing a bra... perfect!
