These 21 It Dresses Will Be Sold Out Come November

We hate to be pessimistic, but whenever we spot an exceptionally good new arrival on our favorite shopping sites, we can't help but predict when it will be gone. A bit of self-preservation, if you will. After all, there's perhaps no more disappointing and all-too-familiar feeling than falling in love with an item only to see those two sad little words pop up: sold out. In the spirit of being proactive, we scoured our favorite brands to pinpoint these It pieces so we (and you) can get our fashion fixes before they're whisked away by others with great taste.

More specifically, with holiday season literally around the corner (we can't believe it either), you're inevitably bound to have ample reason to need a new dress or two. Parties, concerts, plays, dinners, and the like are about to flood your social calendar, so why not make sure you're prepared in style? Scroll down to snag 21 It dresses that we suspect will be sold out by the time November rolls around.
