I wanted something original and funny. This Homemade PMS Pantyliner Costume is what I came up with.
I basically took a huge box (flat screen TV) and cut it into the shape of a pad. I took a mattress pad, purchased from Walmart, for 15 bucks, and wrapped it around the cardboard. Cinching it in to maintain the shape of the pad. I then took two old pillowcases and cut them and put them on the back to look like the tape strip. I also used some of the pillowcase to make suspenders to hold up the pad.
I tri-folded the cardboard so the costume was more compact. There you have it. My P.M.S. costume!
