The key to making head-to-toe pattern work—whether in the form of a jumpsuit, maxi or brocade suit—is to accessorize judiciously. Try not to wear a lot of other clothes (by all means, if it's cold, wear a coat...just make it an understated one!) and keep jewelry to one piece. Avoid big chunky necklaces, especially if you are petite: earrings or a few bracelets are a much safer bet.
While white does look especially nice with Solange's ensemble, it's not the color that makes her pumps a success—it's the style's simplicity. Anything with excessive hardware, too many straps or shiny embellishments is going to look sloppy. Also, if your one-piece is cropped or tapered toward the bottom, I'd go with a sandal style instead of closed-toe one. Without extra fabric to balance it out, traditional pumps will look too heavy under a slimmer-cut leg.
Since Solange has such short curls, she can get away with big dangly earrings, but if you have longer waves or stick-straight strands that fall down to your waist, treat that as your statement accessory. If you really, really want to wear jewelry, however, balance it out with a ponytail or topknot.

Or lips—but you can only pick one! The reason why the DJ's turquoise lids read as cool, not cray-cray, is that the rest of her face is dewy and untouched.
