This week in fashion is a weekly round up of what's being talked about — or bitched about — in Toronto's style scene.

1. Magazines love to throw parties, you know
Following on the heels of Plaid magazine's bash for the release of its spring/summer issue tonight, YYZ Living mag takes over Ultra Supper Club. Get on the list here so that you can ham it up with what organizers promise will be a "who's who crowd from the worlds of fashion, entertainment, finance, sports, and media." That covers just about everyone, I guess.

2. Topshop is one stop closer to landing at the Bay, officially
In case you hadn't heard, The Bay has announced that UK-based, must-have-everything retailer Topshop is setting up shop in its Yorkdale Mall store in September 2011. Until then, they're giving you a taste with the Topshop and Topman Summer Takeover at Queen West and Soho Street this weekend, from June 17 to 19. Get your summer stock of Topshop before everyone else, and enjoy treats and free goods all weekend. There's also going to be a "style off" for a chance at a $500 shopping spree. On June 30, the Bay Queen Street will also offer a special capsule collection curated by street style photographer Tommy Ton as just one more teaser before the big reveal. The Queen/Soho pop-up runs Friday, 12 p.m. - 8 p.m.; Saturday, 10-8; Sunday 10-5.

3. GUESS opens a new Queen St. flagship store
Just as we lost one retailer on Queen (I'll miss you, Esprit), another one sets up shop. Guess is introducing everyone to its new flagship with a big bash and a big cause. The brand's new 5,000 square foot retail space will see a welcome performance by Keshia Chanté and a DJ set by Brendan Canning of Broken Social Scene. Better yet, a portion of the proceeds from first night sales will benefit CANFAR, Canada's only independent charitable foundation dedicated to eliminating the global HIV/AIDS through research. Well done!

4. Party it up at Power Ball
The event on everyone's fingertips this week will be Power Ball, hands down. What's the big deal you ask? On Thursday, a reported 1,700 people will migrate to The Power Plant gallery for its annual fundraiser for Canadian contemporary art. Described as "part social extravaganza, part art exhibition," this year's theme is the eerie Thirteenth Floor, a place you hear about but rarely ever go. Of course, it promises to be the most talked about party - until the end of June that is. Tickets: $165 / $155 for Members of The Power Plant. To purchase, visit thepowerplant.org, call 416.973.4018 or email powerball@thepowerplant.org.

5. TALK OF TWITTER: The MMVAs
The Much Music Video Awards are on their way - and so are all the celebs or something like them. No doubt I'll be talking about who's wearing what and who is where, and you'll definitely be able to style stalk all up and down Queen and King West. For starters, H&M is throwing a massive pre-party this Thursday featuring the likes of Dragonette and a 20 per cent discount. Not on the list? Better win tickets or make fast friends. For the best MMVA Who-What-Wear, follow @trendingtheshow, Much's own What's Hot/What's Not show that looks at what everyone's talking about on Twitter.
