Every time a starlet walks down the runway in one of Zac Posen's custom creations we feel a pang of couture envy, so the celeb-adored designer's made-for-Saks Fifth Avenue diffusion line Z Spoke was a welcome salve. The fall 2010 collection has Posen personality—fun, flirty, and infused with a refined joy—and is filled with flattering, vintage-feeling pieces that can skew girly or grown-up. And the part that has us freaking out? You can get the designer's typical attention to cut and structure at very non-bespoke prices—those waist-cinching dresses start at only $160, and the jackets at $245. Some of the (denim!) suiting is now on our must-have list, so we'll be counting the days until the line hits stores in July.
