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.

You cant go wrong with the base t-shirt bras. The color did not look appealing on my skin, so I returned, but overall, great bra

Comfortable and well sized.

I've run through several "online" bras over the past year. They have disappointed. One had underwires that twisted over time and another had an awkward 3 hook fastener plus removable padding that moves around in the wash.
Harper Wilde has a good system for getting a well fitting bra, adequate cup size (I'm a 34B) and the straps are far enough off the neck so they don't show. I will certainly order more.
My only note is the bra is thoughtful enough to include a set of hooks for a cross back style but I wear a lot of knits and the hooks pull them. (Will eventually cut the hooks off)
This is a well constructed bra. Give it a try.

Perfection

When I tried on the base t-shirt bra, I wanted to cry in relief. It fit like it was made for me, it was comfortable, and it supported. It had to be too good to be true! I washed it, and have been wearing it for 6 hours now. I have a 6 month old, a 2 year old and a 4 year old. I'm moving around, lifting, bending, carrying. I haven't had to adjust this bra once. The straps haven't moved, the band didn't roll, and it's just as comfortable as it was when I put it on 6 hours ago. I'm here to buy more and throw away my other bras that were just "good enough" but not great.

I've been buying the bliss bralettes and figured I'd give the base t-shirt bra a try. I got lucky with my size and hit it right. However, exchanges are super easy! I had read a review awhile ago saying this bra is nothing special. I couldn't disagree more. I am thrilled to have found this bra, and only wish I would have tried it sooner. If you're on the fence, I would 1,000% recommend!!!

I adore this bra. I’ve purchased many in the past, and this will not be my last! The straps stay put without digging in, and the adjustable racerback hook in the back is a super helpful option. I use it a lot for summer tanks! I love that HW offers new colors from time to time as well to keep it fresh. It’s perfection!
