cheap(er) chic: staple white dress

I found it, the perfect summer staple-this cotton white dress (currently on sale for $189) from Karl Langerfeld. It is the perfect blank palette for almost every summer occasion when paired with the right accessories. Add a hint of gold to create a luxe look for evening:

prada bow ballet flats (40% off), grass earrings from anthropologie ($128), metallic leather clutch from j.crew ($98)
Some pops of bold colors and some beaded earrings for a Sunday brunch...

beaded earrings from anthropologie ($88), foldover marc jacobs clutch (50 off%), mystique sandals ($140)
A feminine cardigan and structured bag for your time in the office.
kate spade tote($198), Milly cardigan (40%) off, sam edelman flats ($99)
Do you have a special summer staple or go to clothing item in your closet?
