OH SNAP BARDOCK, BULMA TROLLED YOU.
Bright colors are bright. And colorful.
If you're confused, this is a scene from one of the many comics I'm allegedly working on. Bardock is brought back from Otherworld under a litany of wacky circumstances detailed in the story, but the TL;DR is that these are his "civilian" clothes, courtesy of Ms. Briefs herself. Oh Bulma, will you ever learn? Pink and lavender are not manly.
