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.

Surprised how much I could like a pair of underwear

These feel AMAZING. I had been on the hunt for new cotton underwear and these are my new favorite. They feel soft and have washed well. True to size. I am consistently a medium and that is what I bought here. (5'10"/160lbs). I will definitely be buying more in the future.
