Every girl has a different personality, and they incorporate this into their own sense of style. Take celeb looks from classic Reece Witherspoon or bombshell Megan Fox. Any way shoppers accessorize the party must haves, they can't go wrong.

For the "Rock n' Roll rebels," a strapless satin number in a shade of red, or the always original black, would start the night off with a bang. Check out FredFlare.com or Express to get this look. Think Angelina's dark side, and add a belt to sinch the waist. A leather jacket and a pair of sky-high black heels, or even spikey booties, will top the outfit off. All these accessories can be found at RevolveClothing.com and right now, more than 8,000 items are 20 percent to 80 percent off. This look will get the Brad Pitt type everytime. 

Another take on the perfect party look would be on the "Funky Fashionista" side. Think Miss Lady Gaga, but not so insane. Pieces should be loud and sequin filled, but not too over the top. Try Chickdowntown.com, which has every contemporary designer under the sun, and the "SALE" section is always great to check out. Try a bandage dress (think Herve Leger but in a cheaper version) with accents of bright purple, hot pink and hints of black. Dare to bare and search for a one shoulder dress. Tons of designers have this look online and in stores. Try ASOS.com or a department store that carries BB Dakota. Add a dark polish that looks like OPI's Lincoln Park After dark, and start dancing the night away. Every girl has a different personality, and they incorporate this into their own sense of style.

"Polite and Pretty" is always classic, but this season try being a little more naughty than nice. Ruffles and bedazzle are making their comebacks after being left in the 80s. Ann Taylor, J Crew and Tulle4us.com are great stops for classic yet modern must have dresses. Champagne and satiny pinks look great over simple tights. Add a skinny belt for some detail with a "Party Cardi" from Old Navy, which are currently on sale for $19, and the look is almost complete. Nude patent leather Kate Spade look-a-like heels go with everything. Don't forget the pearls and this look is ready to go.

Lastly, for the gal that is more next door than dress up, stick to the basics. Try a brocaide skirt from Urban Outfitters and throw on that trusty jean jacket over a tucked in white t-shirt. Spice it up with tights and trusty ballerina flats. Comfort is in and high mantinence is out. Navy also works well with the season, so throw in a boy-meets-girl blazer from Gap and a headband with slight detail to switch things up. All women have a little girl-next-door in them.

Whichever is preferred, these looks cannot fail. Check out InStyle.com for more party dresses that are $100 and under.
