1. Smoothing Hair Cream

Ashley's hair looks perfect! Not too sleek, not too tousled, and no frizzies or fly-aways. We don't know how she does it, but we love this After-Party Smoothing Cream from TIGI ($15.99, drugstore.com). It smells sexy, and works like a charm.

2. Long Tank

If you're wearing an oversized top as a dress, layering is a must! Try a long, black tank underneath like Ashley did -- if not for style, at least for practicality. (Your bare legs may get cold, but you might as well be warm on top!).

3. Cinched-Waist Tunic

Yeah, we totally dig Ashley's sheer, shimmery shirt. It's definitely one-of-a-kind -- literally. Which would explain why we couldn't find anything quite like it! But we think this top comes close ($26.50, alloy.com).

4. Cute Clutch

Having a hot, grab-and-go purse is a must for parties! We like Ashley's cuz it's totally stylin', but doesn't take away from her chic outfit. Get a grip on this similar clutch from Alloy ($29.50).

5. Mile-High Heels

If you're gonna show off your legs, why not go all the way? As long as you're comfortable walking runway-style, super-high heels will glam-up your gams! For the same black-on-brown look of Ashley's pumps, try these on for size ($29.50, alloy.com).
