The Gown by Oscar de la Renta collection spring 2010. You don't have to wear white on your wedding day. That's what we think anyway, and from the looks of the collections this season, so do many top designers. And we're not talking colored sashes and floral embellishments. Instead, we saw large swaths of colored fabric playing a major role in the gown's overall design, from subtle pastel chiffons to lusciously saturated silk taffetas. Blush pink, silver, and pale blue have been bridal-friendly for a while now, but this season we were pleased to see shades of yellow, purple, and green make their debut. You'll see that some of our favorite designs are more radical than others, but even a whisper-soft wash of color can take you from looking good to looking absolutely radiant.
