On a Thursday evening just before the holidays, Rachel Sheehan put out some doughnuts and grilled cheese sandwiches and invited Dundas Westers into her new vintage clothing boutique, Penny Arcade. Between bites of Crock-Pot mac 'n' cheese, shoppers sampled retro picks ranging from Oscar de la Renta blouses to acid-wash miniskirts. Somehow, these killer Mary Popps 80s pumps got left behind. They're 8½. Ready. Set. Go! $65, 1177 Dundas West, 647-346-1386.
