Black skinny jeans, maybe heels or flats and a nice top with earrings is always a good combination for parties and for makeup, something subtle, maybe smokey eyes if its at night but nothing too heavy- just something smart/casual and cute...if you want to wear a dress, forever 21 do a lot of cute and inexpensive cocktail dresses, and maybe doing somethign cute and fun with your hair, like straigntening it (or making it curly if its straight!) could also be an idea...but never TRY to look sexy, it hardly ever works! xxx
Too many women tend to overdress for such occasions, which is definitely a turn-off for me. I suggest simply wearing a hat.,This is sure to attract wanted attention, yet doesn't send any negative messages such as you might be overbearing, or too picky. Easy on the pocketbook as well.
dark wash skinny jeans and a top that shows off your best features while hiding insecurities. Top it off with unique accessories and shoes that are comfy but hot. If its a dressier party, I would op for a dress, but I wouldn't wear a dress to a house party or anything its too dressy.
