Maybe!! Like the long fluffy ones. [Gon laughs at the imagery,then grins, his response, as usual, maybe a touch too sincere.]

Killua, you'd look good in anything. Even stupid stuff.

[which, you know, Gon doesn't understand anything about fashion—as far as he's concerned, he's already seen Killua in some unjustifiably stupid stuff, so it's not....really all that different. but Gon at least gets that hats are, objectively speaking, goofier than most accessories on principle.]

You'd look cute in a more simple style witch's hat, too...
