Think back to simpler times. When important decisions were made with rock, paper, or scissors. When love was debated on notes passed in geometry. When everyone was a winner. People, gather today to put a stop to all this growing up madness. (You know, assuming responsibility, paying bills, wearing work-appropriate attire.) Retaliate with Mooka Kinney! Who? No, what: a whimsical, childlike line of frocks (without any creepy Lolita overtones). You might be tempted to throw a tantrum for the collection of pinafores with suspenders. Or (heaven forbid) wet your pants over adorable patterns (swans and mod florals) and little details (buttons shaped like deer, strawberries, and ponies). Casual empire-waist dresses make fine tea-party apparel. Sweet baby doll tunics are just right for playing house. Of course, the dresses look just as fantastic in grown-up situations. We kid you not. Available at I Heart, 262 Mott Street, between Houston and Prince Streets (212-219-9265 or iheartnyc.com). To see styles, go to mookakinney.com.
