While grabbing lunch in LA with her boyfriend, Michael Polish, Kate Bosworth showed off her breezy, bohemian Summer style in a brown printed spaghetti-strap dress. But what really made her look pop were her tan accessories: a Ralph Lauren saddle bag — shop the lighter version here ($1,163) — a tan studded belt, which lent shape to her waist, and tan ankle-strap flat sandals. Matching accessories can sometimes look too contrived, especially if it's a bright color, but we love that Kate chose tan for a subtle approach.
