What: Forever 21 Satchel

Why: Every woman needs that one {or several!} satchel for day to night. It's large enough to fit your essentials, and it's not too bulky for a night out. While I'm pretty much obsessed with Forever 21 skinny jeans because they stand the test of time and don't get the dreaded crotch rip, the affordable retailer also has some amazing satchels for the season. If there's one bag you want to buy now and carry it through fall and winter, this is it. Oh, and you won't spend more than 30 bucks.
