This Week in Fashion rounds up the week's style news, store openings and closings, pop-up shops, sales and upcoming fashion and design events in Toronto. Find it here every Wednesday morning.

NEWS

Square One (100 City Centre Dr) may already be smack in the middle of an expansion, but that doesn't stop Oxford Properties from planning yet another $320 million mall facelift - this time anchored by a 120,000 square foot Holt Renfrew store. Renderings released last week by architecture firm Janson Goldstein show a honkin' glass exterior and a reworked road map.

Young & Tae, a Seoul-based shoe brand owned and operated by power couple Jenny and David Kim, opened its first brick-and-mortar store right here in Toronto last week. The minimalistic Queen Street boutique (630A Queen St W) offers a wide range of fashion-forward footwear for women, including red leather riding boots and ultra-sleek slingbacks.

Gravity Pope (1010 Queen St W) recently opened up their basement to house a pop-up teeming with potential gifts for everyone on your list. Running through to the New Year, the one-stop shop has all the fancy doodads one could ever desire, like Quill & Tine touchscreen leather gloves, Santa Maria Novella apothecary, and - best of all - Cubebots!

Until the end of December, get your hands on Lucian Matis' newly launched home decor collection at Shops at Don Mills. The pop-up shop - located at 23 Karl Fraser Road - will be filled to the brim with discounted lavish fur pillows and trash bins, as well as clothing from his eponymous haute couture line and lifestyle collection.

EVENTS/PARTIES

If you're nowhere near finishing your holiday shopping, don't stress! Oz Studios (134 Ossington Ave) is throwing a shopping party/pop-up shop tomorrow (December 19) from 6 pm until 9 pm so you can get your groove on while stocking up on Dylanium Knits, Skinny Sweats, Laborde Jewellery, and Homegrown Boutique's Canadian fashions. If you can't make it out to the launch, the pop-up shop will be open through the weekend to fulfill all your last-minute shopping needs.

You can also check out our round up of holiday craft shows and events here.

Headmistress, a local brand offering headdresses ranging from floral crowns to feather headbands, is hosting their second annual holiday pop-up shop tomorrow (December 19) from 7 pm until 11 pm. For one night only, head over to Hermann & Audrey (1506 Dundas St W) for a drink, a treat, a visit from Santa, and 10% off all of the accessories you'd need to stand out in a crowd or stuff in somebody's stocking. RSVP to RSVP@loveheadmistress.com.
