1. Pendant Necklace

Wanna dress up your outfit without going overboard? Add a pendant necklace like Kristin did! We like this cute owl one ($16.50, alloy.com).

2. Ribbed Tank

You can never have enough tanks! Whether you wear 'em separately like Kristin -- or underneath your fave sweater, you can't go wrong. Get two for the price of one from Alloy (2 for $12.50).

3. Chunky Bracelet

Adding a wide wristband to your casual ensemble can add a lil' edge. Instead of something delicate, opt for a chunky bracelet like Kristin's -- or this one from Delia's ($14.50).

4. Destroyed Skinny Jeans

It's all about the holes, baby! If you want that "I'm not trying too hard" look, go for destroyed denim like Kristin did. You can snag a lookalike pair -- on sale -- at Alloy ($37.20).

5. Leather Boots

This outfit would be decidedly less hot if Kristin wore her jeans over her boots. (If you're gonna wear a cotton tank with jeans, you gotta rock the footwear!). Check yo'self with these boot-iful boots ($69, delias.com).
