It's the last day to enter our giveaway! Fall shopping is in full swing, we're changing up our wardrobes, and our sixth sense for those covetable must-have items is sharper than ever. We're craving glamour for Fall, via a lace dress, embellished purse, and the season's most indulgent fabric: velvet. On the flip side, we're catering to our more casual, edgy-cool side for pieces that will carry us through the everyday — an insanely cozy Helmut Lang sweater, snakeprint oxfords, a unique bracelet, and just about the coolest investment piece we've seen: Thakoon's oversize tweed vest for layering and statement-making. Click our editor's picks to see what we can't live without this September. Then, at the end, vote on your favorite to be entered to win a selection of our September must haves plus a selection of monthly favorites from other PopSugar sites. The giveaway ends TODAY, Sept. 30 at 11:59 p.m. PDT, so don't procrastinate! Get detailed rules and start voting.
