1. Sheer Lip gloss

You don't have to layer-up on red lipstick to be sultry. A clear, shiny gloss like Cassie's is just as hot! Plus, you don't have to worry about smearing. Try Maybelline's Lip Polish in Crystal Clear ($4.11, ulta.com).

2. Striped Tunic

Black-and-white is never out of style! If you wanna show off your shoulder, go for a tank like Cassie's. Otherwise, warm up in our version ($9.99, alloy.com).

3. Gold Bracelet

Nothing goes with black like gold jewelry! Go for the gold with a wide bracelet like this one ($19.50, delias.com).

4. Black Pants

Love wearing skinny black pants like Cassie? Try on this silky sateen pair ($29.50, alloy.com).

5. Chic Booties

Ankle boots are in style -- and lower than ever! If you're itching to try out this trend, pick up a pair of these Holiday Booties ($39.50, alloy.com). They have a detachable ribbon on the back. Fun!
