Constructed with the same Organic Cotton/Spandex as the Thunderpants, this bralette is super comfy. There is a piece of elastic sewn into the binding for extra support below the bust. It feels supportive and solid, without feeling constraining or too bra-like. You can consult our fit guide here or find the matching Thundies here.
Thunderpants 90% organic cotton/10% spandex fabric is sturdy, very stretchy, and has great retention to give our garments just enough stretch and bounce back. It helps the undies to stay up and on, and the other garments to keep their shape without sagging or bagging. We use the same soft organic cotton blend to cut our binding into a wide strip instead of using elastic so their is never any irritating elastic against your skin. All the garments are made locally and lovingly in Portland, OR.
To preserve the vibrant colors and life of the fabric we suggest you do not soak or bleach your Thunderpants items. Use a gentle detergent in a cold machine wash and dry your Thunderpants on the line (they will survive drying on low, but may fade a bit and cut down slightly on longevity). If you do wash warm or dry, make sure not to use too much heat as heat will break down the spandex!
All our prints are designed by artists and are limited edition. They don’t stick around long, but there is always something cute on the way!

Please make a narrower strap bralette
I think this bralette would work better for bigger busted women than me (I'm only a B cup). As it is, the straps rub my armpit too closely, so I returned it. Otherwise, the fabric is as lovely as their underwear. If Thunderpants ever makes a skinny strap bralette, I'd be all over it.

Undies that bring me joy!
The new green thundies are delightful! I forgot I had them on (because they are so comfortable!) and went to change and the bright green was a spot of sunshine in my day!

Wanted to love it
I really wanted to like the bralettes due to their looks and the wonderfully perfect fit/comfort of the panties, BUT the side seam digs in and causes discomfort. I have 2 bralettes and both have the same issue. If not for the seam, it would be perfect. Unfortunately, unless they find a fix, I would not purchase again. The panties, however, are the most comfortable I've found and will happily purchase more in the future.

Comfortable bralette
Cute pattern, perfect fit, well made. Will buy again.

Terrific fit
This bralette is so comfortable. This is the only bra that does not cause me itchiness.
