There's nothing quite like a trusty LBD - a piece you can always count on to dress up or dress down and wear in pretty much any and all situations.  I have several go-to LBDs which have brought me through pretty much any situation out there.  This one, I snagged over five years ago (?!) at Banana Republic and thanks to my girlfriend's trusty eye.  I wore it when I was pregnant and I continue to wear it today - it fits just right and looks great on all of the time.  It's a classic piece like this that I always recommend people beef up their wardrobe with.
