So confused about the measurements!!!

  1. i got a white muse off let-trade and i don't know what size it is. this is the measurement:

    15.5" x 10" x 4"

    is this a large or OS/XL?
  2. OK NM.

    it's a medium. the measurements were off.

    will this look funny on me?

    i'm 5'5" and i wear 4" heels everyday... i hope it doesn't look like i stole my little sister's purse!!
  3. Can you post a photo?
