Fleabag From Fleabag What to wear: Leave your filter at the door and throw on your favourite striped tee when you step into the character of Fleabag. This dry-witted woman keeps people on their toes, so be sure to do the same. If you want to make this into a couple's costume, dress your partner in a priest outfit, and you two are ready to take on the town! Image Source: Everett Collection
