Lucky and Grimm Bonez (aka Gab and Dan) have nine cosplay tips for convention season. Get good (comfortable) footwear, learn how to go to the bathroom in your costume before convention day - if there's no way then install a bathroom in your costume, magnets are an unexpected best friend, you don't need to buy expensive fabric to make it work, stay hydrated, wear sunscreen, YouTube tutorials are your best friend, put pockets in your costume, and buy food. Have you got anything to add?
