If you're itching to dress like a dapper '20s something, play croquet, and dance to live jazz, you are not alone. The Spadina Museum has received an unprecedented response to this year's Gatsby Garden Party invite. As of this week, 20,000 people have clicked attending on the events' Facebook page.

The literary party takes place each summer, and 2014 saw 1,000 or so costumed revelers attend. This year's massive response has been a bit of a curve pearl for the city, who now have to ready themselves for some disappointed Gatsby fans (the event has never sold out before), even if only a fraction of the online attendees will in fact show up.

So far as the museum knows, the response is genuine - they haven't noticed any out-of-city coverage that could have generated disingenuous clicks. Interest in the event has been gaining momentum each year thanks to word of mouth, a spokesperson from the museum tells me. (Leftover hype from the 2013 film, and the low $5 ticket price, are also likely at play.) The city was unsure of the capacity of the grounds when I spoke to them.

Due to masses hovering above the valley of ashes, the museum has announced they'll be attempting to sell tickets in advance for the first time ever, but can't be sure this will work out - meaning you may have to stand in line in full costume early on the morning of the party. "Just keep checking our website and the Facebook page," museum staff advise.

The Gatsby Garden Party is June 28th at the Spadina Museum.
