The Inspiration: Ok, so this one’s more of a DIY–but one of the easier, more creative ones! Have your own fashion grievances? Let them out with this Hedi Slimane-inspired costume: An open letter! Cut holes in the pillow case for your arms and head. Address the “envelope” to EVERYONE, return address ‘YSL,’ and put on lots of stamps. Bonus points if Lady Gaga tweets about it.

The Formula:
• Fabric paint
• white pillowcase
• Lots of stamps
