Varsity has been a big trend over the past few months and I don't see it going anywhere soon! I really like the vintage style varsity jackets & letterman sweaters you can find all over the racks (my favorite places to shop varsity are Forever 21, Delia's, & Alloy). Although this may seem like a trend targeted towards younger crowds, my favorite way to wear it is to make it look more "grown up". The key is to keep it from looking too "school girl". Here's a look I put together that I'd even wear to work (just replace the distressed denim with a sleeker dark, more dressed up pair).
