Afternoon ashtanga was in full swing in the convent courtyard, so Sisters Mary Margaret and Mary Josephine decided to take their afternoon stroll in Bal Harbour. “Heavens, how adorable!” Mary Margaret exclaimed as she spied a dress from clothing line Sretsis in Intermix. “I love its flirty fit and perfectly placed piping — and the carousel horse print is such fun yet still sophisticated.” The saleslady complimented their keen fashion sense and pointed out Sretsis is actually sisters spelled backward. “It must be a sign,” exclaimed Mary Margaret, “that I should buy this dress for Linda at the orphanage.” And so the sisters headed back to the convent, dress in hand. “I had to pray for the strength not to buy the entire line,” sighed Mary Margaret. “Did you see the perfect little black dress with the puffed sleeves and scalloped hem? You know how I love dressing the needy.” “Oh, yes,” agreed Mary Josephine. “But let’s not make it a habit.” Available at Intermix, 634 Collins Avenue, Miami Beach (305-531-5950); Bal Harbour Shops, 9700 Collins Avenue, Bal Harbour (305-993-1232).
