It's that soiree-hopping, champagne-swilling, festive-dressing time of year, and, for me, it officially kicked off last night at a dinner party at the Chateau Marmont. (I'm the fourth one in on the left, digging into my salad! You can see more pics here.) I scrambled to get dressed for the evening (as per usual!) and ultimately chose an elegant vintage (Gucci-looking) pleated lace-trimmed dress, given to me by my aunt, and while I was happy to wear it, I did think it would be nice to have several more options in my arsenal this season. This morning, I poked around and found a slew, including these by Tamara Mellon, Stella McCartney, Bec & Bridge, Self Portrait, McQ Alexander McQueen, BB Dakota, Haney, and Gucci. Fortuitously, Moda Operandi is staging a half-off sale on tons of fancy party-bound pieces, such as this Thakoon Addition floral print maxi dress, this J.W. Anderson one-shoulder top, this strapless Derek Lam 10 Crosby corset and this Saloni fluttery frock. Enter HALFOFF at checkout. View the all the sale offerings here.
