It’s hard to say goodbye to summer, but seeing the gorgeous trends that fall has waiting makes it easier to put away our bikinis. For 2008, we can’t wait to find ways to mix the two p’s, purple and plaid, into our closets—designers from high to low are offering takes on both. Of course, if there’s one item of clothing that never goes out of style in any season, it’s jeans. Hands down, our favorite denim for fall is Levi’s latest trouser jeans. With a low waist and long flared legs, they’re inspired by menswear but still deeply feminine. Wear them straight from work for a night on the town, paired with a checkered top and bright cardigan, a dangerous-looking pair of architectural heels, and a conversation-starting cocktail ring. We’re already counting the days until the season changes.Tilted Trouser JeansBDG Plaid Button-Front Boyfriend ShirtBebe Ruched Sleeve SweaterL.A.M.B.
