    At JstBU (the text acronym for "Just Be You") we design body-confident undergarments for tweens that will take her comfortably from school to activities, all while empowering her to be her best self. Each undergarment has a special, feel-good graphic message printed INSIDE just for her - to remind your tween of her strength and confidence. 


    Being moms of tween girls, we felt there was no trusted premium undergarment brand that moms and girls can consistently turn to for high quality soft, comfortable fabrics, such as organic cotton and our exclusive cotton luxe seamless. We also wanted to offer age appropriate options with a superior fit for the developing girl. And voila, JstBU was created to fill this void.


    At JstBU we use our power to empower! With every online order, we donate a portion of sales to organizations that empower young women through our "Girl on Fire" program. Read more about this program here.


    Shopping for a first bra for a young girl and mom is an emotional experience. At JstBU we want to make it as easy and seamless as possible. Also, puberty can be an emotionally vulnerable time for young girls, so we hope our special messages will remind them to hold their heads up high. 

     JstBU because  is just as important.
