Hands down the most comfortable underwear ever designed for girls, our Bella Briefs are crafted with ComfySeam™ bonding technology. Instead of being sewn together, our super soft tri-blend fabric is fused together using advanced adhesives—bringing high-end sportswear innovation to kids undies for the first time.
The result is barely there seams that are practically stitch free, except for a couple of minimally stitched areas for reinforcement. The Bella is soft and smooth, with a fit that is absolutely perfect every time. As one of our little reviewers exclaimed, “It’s like wearing a cloud!” We couldn’t have said it better.

What customers say about Bella

Our daughter has ASD and fabric sensitivity. We went through five recommended brands before stumbling across these underwear. They are the first underwear our daughter has worn in almost a year. We are so happy, and she is so happy and comfortable! These are amazing! We can’t say thank you enough.

Huge fans of your brand! My daughter doesn’t care for this new stay. We will be sticking with the original bikini undies.
