9. Event T-Shirts
The thing to do at university was design, buy, and wear tees for any and every event you attended. And while the habit resulted in a trove of tops to wear to the gym and on errands, they become a bit dated the minute your diploma is in hand. Donate and free up drawer space for all the new memories you'll make.
10. Casual Sweatpants
Let's be clear: we love slouchy, fashion-forward sweatpants worn with heels (we're looking at you, Kate Beckinsale!). But the oversize pair your stole from your boyfriend junior year? Or the velour flares with the pockets? Wear them all you want while sipping coffee at home Saturday morning, but resist the temptation to bring them out in public.
