Hi Angela,
Very sorry that your jersey didn't fit as you would've liked. We do recommend getting sizing advice with us before you buy as the same item fits everybody differently. If you get in touch with us at fatlads@fatladattheback.com then I'm sure we can sort this out for you. If the item hasn't been worn and still has it's tags then we can offer you a refund or exchange, please let us know if you'd like to do this.
