I don't think brown is always boring, and if it really suited you, (the colour not the dress) then it would be worth looking at other stuff in brown..... but you would have to wear bright colours with it, like red or purple or bright green! It isn't really a party dress colour, deep velvety blue, purples, greens, reds and black are all good party dress colours.
What is your colouring - hair, eyes, etc. ?
