When I cosplayed as PB, I chose her "Susan Strong" outfit purposefully because it's up in a bun and I wouldn't have to deal with the wig XD
My friend is actually working on LSP right now--we had a blast brainstorming methods for makeup, her trash-bag dress, etc
She's even planning on adding a mustache and multi-tasking for Lumpy Space Prince, lol.
