What if boxer briefs were designed for our bodies from the beginning?
How Blu started

Where it started

"I sleep in my boyfriend's boxers." "They're just easier." We kept hearing it from friends, and from queer friends who found them more affirming, too. Just never made for either.

Where it's made

We developed the first cut with a designer in Berlin, then spent months finding a factory in Portugal willing to build it properly with us. Designed for women, non-binary and trans people, and anyone else who wants in.
