Base T-Shirt Bra

How to measure
1 Full Bust

Wrap the tape measure around your back and across the fullest part of your chest, ideally while wearing a lightly lined bra. Make sure to leave enough room to be able to take a full breath.

2 Underband

Measure the area directly under your breasts, around your ribcage. The measuring tape should be snug, but not tight.

Very Comfortable! One of the Best Bras I've Bought!

I've never owned a bra this comfortable or that fit this well before. I love that it has the adjustable strap in the front. It's very convenient and makes it so much easier to wear. The bras overall provide good support and coverage, the band doesn't dig in like a lot of bras making it easier to wear for a good portion of the day.

Doesn’t poke!

I always get poked by underwire bras. I spend the first couple of wears bending the wire—I know, it’s bad for it, BUT. I didn’t need to do that to this one. We’ll see how it wears long-term, but so far so good.
