Absolutely LOVE my Spaceship Earth fanny pack! I wore it all day yesterday in EPCOT for the Food & Wine Festival and it was very comfortable. The pouch holds lots of stuff (even my tiny umbrella!), but isn't too big. Being a size 6, I wasn't sure what size to order since I fell in between sizes, so I went with the S/M. The fit was perfect with a little extra room (few inches comfortably with a sweatshirt). If you are over a size 6, I would go with a M/L. LOVE this product and I will be ordering again soon! So many fun designs to chose from!
