Fab or flop: Rosie Huntington-Whiteley's suit, Kate Hudson's overalls and more

Color us surprised! Kate Hudson nearly always looks absolutely flawless, but made a rare misstep this week in a strange, ill-fitting ensemble that severely contrasted with her typically sleek and sophisticated looks. While we're not fans of this particular pair of denim overalls, they may have worked better with a more form-fitting, structured top instead of the frumpy knit she opted for.

Karlie Kloss also should have known better when she slipped on a dramatic, floor-length high-low lace top with wide-legged pants, sneakers and bodychains.

Rosie Huntington-Whiteley, on the other hand, nailed it in a sophisticated and chic look in London. The model, 28, looked absolutely timeless in a gorgeous navy suit with a slim pantleg and knee-length jacket that accentuated her statuesque frame. A crisp white shirt completed her classic look.

Taylor Swift was also one of this week winner's in an edgy black look that marked a departure from her usual colorful, kitschy ensembles.

See these looks and more in the slideshow above.
