-Just plain old boxers

-Solid colored

-Also plain old boxers

-He's a little more fashionable than Gon, though, so his will be patterned or plaid

-He thinks about which ones he wants to wear every day rather than just grab any old pair

-Hangs out in wife beaters a lot

-Rather fastidious about his underpinnings

-Wears boxer-briefs and prefers white or tan-colored ones

-He has a lot of crisp white t-shirts too and likes them to be spotlessly clean, so he goes through a lot of them

-He'll wear anything except tighty whiteys, because he has a complex about being an old man

-He thinks only old men wear those kind of undies

-He has zero opinion on underwear aside from that

-Usually just skips underwear completely, TBH

-That's our boy!

-Wears a jock strap

-He's gotta be careful, y'know?

-He's got a pretty dangerous, athletic job

-Gotta keep the Zoldyck family jewels intact

-He has various styles which he switches around depending on his mood

-Prefers them to be all black

-Likes quality, won't buy cheap undies

-He has this pair of black silk boxers that are really hot

-Nobody knows really what kind of underwear Feitan wears

-He keeps these details to himself

-When hanging around at home, he is shirtless and in his loose black pants all the time

-What's underneath?

-He says if it's so important, come see if you can find out for yourself

-Don't tell Kurapika, but he also likes boxer briefs

-He doesn't care what color they are, though

-He has a perverse hatred of any sort of novelty prints, however, so don't buy him any with palm trees or smiley faces...or spiders even
