Rachel Roy is capitalizing on this spring's rainbow-color trend with this beautiful silk faille "tulip" dress in bamboo print.   Staid enough in cut for the office, but cheery enough in color for a date, this is a very wearable day-to-night piece.  Pair with bright shoes and some pretty bangles and you might be able to make it a night-to-day piece by eliminating the shame from your walk.
