Besides the LBD, I highly recommend a simple, chic blazer to add to your collection. A great blazer, especially from a suit set, can make almost anything work appropriate (yea, not anything, but you know what I mean). Invest in a good one to get a good cut and a blazer that will last you awhile in wear and classic style.
