If you've ever wanted to experiment with pretty pleats, now's the time. Accordion pleats are cropping up in unexpected places. They're a classic take on texture, but don't think these pleats signal school girl. They're playful and fresh in other fabrics, like chiffon, à la Jessica Alba in Marc Jacobs, or even a little naughty in leather. Whether you select them as a part of the whole look, or just to experiment with the details, they're modern and femme, and insanely flirtatious.
