My SIL wants a bag for Christmas but we have a limit on spending. So is this doable? She wants not huge, but big enough to throw her stuff plus a diaper and wipes in. She is not a handbag person (otherwise, she would buy one herself, right?? lol) - she has been carrying the same pink nine west fake leather bag for 2-3 years... So I was thinking black, medium sized, shoulder bag, easy to get in and out of...is my main option TJ Maxx?? Thanks for any suggestions!
