Personally, my eyes head straight for tiny, cute, little gauzy pleats that fill the garment from head to toe and end up looking like a pattern with tons of texture. Like this Halston dress that I have been drooling over for what seems like forever now (the dress, not the shoes).
Not sure how to wear? To avoid looking too prim, proper and preppy, try balancing the ensemble with something that has more of an edge. For example, pair with black (or gold) lacquer leggings, a nubby vest, a beat-up leather jacket (try camel or cream!) or even a sweatshirt (as seen below). Similar to a home, mixing and matching different styles is a must to get that eclectic, effortless look that becomes simply your own.
Here are some of my (more affordable) faves.
modcloth (with gold leggings and heels)
anthropologie (sub the sash with a thick, woven belt)
gap (add a large, shiny ornate brooch)
lulu's (notice the belt and add a blazer)
zara's (sub the leather belt for a tassle belt)
urban outfitters (tuck into a tweed pencil skirt)
topshop (wear with that nubby vest!)
free people (maybe lace up boots?)
