Getting ready for prom can be a nightmare. Figuring out your hair and makeup, trying to find the right dress, avoiding duplicates and convincing your mother that you’re old enough to be a little sexy. Prom was once about the puffy tulle dresses and lots of frills and sparkles, but styles are now sexier and sleeker. Thank goodness. Avoid looking like Strawberry Shortcake in a cupcake dress. Be sexy without looking tacky, trashy or cheap; the dresses and make-up are sure to get you and your prom date laid, just make sure it’s not your first date

We love this sheer gown by Carlos Miele from the Spring 2011 Ready To Wear Collection. The dress is somewhat of a body suit with a sheer overlay that falls into a floor-length gown with one sheer sleeve. With sequined designs that look like a game of pick-up sticks, this look will definitely acquire lots of compliments.

If you want a more elegant look, we like this pleated gown by Tadashi Shoji with crumpled blousons across the shoulder and growing from the bottom hem of the dress. It looks like an Anthropologie window display.

If long gowns aren’t your thing, snag American Idol’s Pia Toscano’s look from Elton John week. Pia wore a a sexy sheer stone embellished dress by Jovani. The long-sleeve mini dress in sheer nude is embellished throughout with stones covering the right places. Just in case you actually want to cover up, the Halston Heritage Fur Coat in Natural is a fashionable piece, not like the typical cover-ups from back in the day. It would go especially well with a leg-baring frock.

Hair and makeup. This is where things get touchy. Yes, you may want to get laid on prom night, but no need to look like a floozy. Not cute. We love the looks of Katie Cassidy, Zoe Saldana and Isla Fisher.

Katie Cassidy’s hair is a modern take on the updo, and looks especially polished with highlights. Her curls are pulled back from her face with a few strands out of place.

Her makeup is natural with a subtle smoky eye. To achieve this look, use MAKE UP FOREVER PROFESSIONAL Uplight Face Luminizer Gel, an oil-free gel that gives you an all-natural glow. The product is available in dewy, pearly and sparkling hues and can also be used on the body for a sun-kissed glow. Dust cheeks with the Guerlain Terracotta Bronzing Powder and a little on the bridge of your nose.

Try the Too Faced Naked Eye Soft & Sexy Eye Shadow Collection for the seductive eyes. Dust a neutral color over the entire eye lid up to your eyebrows, the dust the lid only with a steel grey shimmer. Apply a matte ivory shimmer to the inner corner of your eye, and mirror the ivory with a matte black. Line your eyes with Bobbi Brown long-wear gel eyeliner in jet black. For lush lashes, apply two coats of Stila Glamoureyes Mascara. For your lips, try Benefit Ultra Shines Lip Shine in Foxy Lady.

Zoe Saldana always look naturally gorgeous. If you want to wear your hair down for prom, opt for cascading curls. Be careful, you want loose, voluptuous curls, not Shirley Temple ones.

To recreate her look, brush Smashbox HALO Hydrating Perfecting Powder over your face. Dust a cotton candy tint on your cheeks such as NARS Blush in Angelika.

Keep eyes natural with LORAC Starry-Eyed Baked Eyeshadow Trio. Dust the neutral color over the entire eye from the lid to eyebrow, followed by the darker color on lid. Highlight under your brow with a shimmery hue.

Line your eyes with a precise liquid liner such as Lancome Artliner. Lengthen lashes with two coats of Lancome Definicils mascara. For lips, try Givenchy Printed Lips Tinted Look Lip Stainer in Rose Impression.

Isla Fisher’s hairstyle is a simple, yet elegant style for prom. Part hair on the side, tie the hair back away from your face leaving some pieces in the front to frame your face, and curl those pieces away from your face with a curling iron.

Fisher’s makeup is a great prom look, a rosy-bronzed mix. Apply MAC Studio Fix Powder Plus Foundation to the entire face for an all-matte full-finish coverage that last for hours, followed by Tarte Natural Beauty Cheek Stain for long-lasting rosiness. Long-lasting makeup is a must because you never know where you will wake up, and you want to remain flawless wherever it may be.

Accentuate your eyes with gold and bronze tones. Try the Urban Decay Naked Palette for great color combinations. For voluminous lashes, apply two coats of Dior ‘Diorshow 360′ Mascara. Your lashes will almost look like falsies. Use a berry color on your lips such as Laura Mercier’s Lip Glace in Rose.
