There is no shortage of interesting-looking bottoms on offer in stores. Whether it's a pair of pants or a skirt in a sheeny satin, a metallic brocade, taffeta or something in sequins like these pants from outnet.com the best way to create a look for cocktails that won't appear overly fussed and trussed is to keep things simple on top. Of course, this is when the ubiquitous crisp white shirt comes in handy for a high and low mix but I like the casual drape of a dead classic cashmere V-neck or turtle neck worn with a statement bottom and some serious-looking faux gems.  Try a set of cuffs one on each wrist like Ann Taylor's  Swarovski crystal-encrusted eye catchers and a pair of dazzlers at your lobes like this pair by Lee Angel. Or fill in a low v-neck with a statement necklace.  I will leave my Gaucho hat and sunglasses at home however.
