It’s All In The Stitch Los Angeles-based designer Marco Marco initially made a name for himself designing clothes for Katy Perry and Britney Spears... but he’s really made his mark on the world of men’s underwear. The Neon Stitch Collection feature briefs and boxer-briefs that amp up the drama, with neon piping that reacts to UV light. From go-go boy… to glow-glow boy. That’s a story we’d pay good money for.
