I'm looking for a new bag,big enough to keep nappy and wipes in but not too big as will be used as a handbag. I likethis style but want something a little more handbag like. (However am not a girly girl so nothing too twee). Needs to be long across the body type strap. I'm a bit stuck as shopping isn't my thing. Budget up to about £60 as want to keep it for a long time.
