dress dilemma.

well...i have been searching for a dress to wear to this wedding next weekend. i have probably been searching regularly for the last month and can't find anything!! i don't know, maybe i'm just being too picky: i don't want something black (i always buy black dresses), i want a spring-y color but i don't really like floral patterns, i want something modest but not frumpy, oh and i would prefer something under $50, etc. every time i go out looking for a dress it's hard to find a fashionable modest dress - if it is really cute with sleeves it is usually too short, or if it is long enough then it shows too much cleavage, or then (random dress!) i found a super cute dress with sleeves and long enough BUT the arm holes were way too big!! i'm having other random issues because most of the "woman" clothes don't fit me and then the "juniors" dresses are kinda cheesy so even when i find something it doesn't fit either. i am about to give up and just wear something i already have (boring) unless someone is willing to help me out with some ideas! i have a week left to find something...
