For some reason, twice a year, women feel the need to wear as little clothing as possible. Those two occasions are Halloween and New Year's Eve. While many women bask in the glory of feeling justified for being scantily clad, many of us would rather keep a little to the imagination. Seeing someone's butt cheeks hang down from under their dress veers off the sexy path and into, "WTF is she wearing?" So, to avoid such disasters, here are 4 looks for 4 different types of parties that are both sexy AND classy. Whether you're headed to the club or out with the family, here are some pointers for keeping all eyes on you for the right reasons.

New Year's with the Family

If you're headed out with the family or your significant other's parents, now is not the time for that skintight disco ball dress. Keep this ensemble simple and chic. A longer hemline, higher neckline, simple accessories and classic colors work best.

A Black Tie Affair

Black tie affairs are my favorite. These are the events where you can pull out all the stops. The full length gown, jeweled shoes, gloves, decadent jewelry. This is the night to go into full movie star mode. Try a Grecian, embellished dress and go for color. Any color but black or white (to avoid looking like a runaway bride or Morticia). This is the night where you can never be too overdressed. Think Audrey Hepburn or Marilyn Monroe.

Poolside New Year's

For all you lucky ducks who will be in warm weather for NYE, channel the weather with an airy ensemble. If you're by a pool and it's 75 degrees, go light and fun. Don't be afraid to go for lighter colors that are normally reserved for spring, but make sure to add a little New Year's glitz to it.

Up in the Club

Without a doubt, this is where many of you will be. The word "club" is synonymous with dancing on the table in a micro mini. If you don't want to be "that girl" but still want to look ultra sexy, go for something shorter and glitzy, but keep the accessories at a minimum. (i.e don't combine with glittery shoes, knee high boots, chokers etc.) And also, ya know, stay off the tables.
