Say you are in town for a certain convention and have long admired the stylish fits of a certain former first lady. It’s time to get acquainted with Maria Pinto (that’s her, pictured above), Michelle O’s go-to designer throughout her husband’s presidential run (who can ever forget that ocean-blue 2008 DNC dress?). Pinto’s designs aren’t reserved for just political power players. Her new boutique in River North is all about catering to busy women. That translates to ready-to-wear pieces, from A-line dresses to sleek suits, all machine washable and travel friendly. And if you happen to pick up a body-grazing jewel-neck dress worthy of the Governor’s Ball, well, all the better. 710 N. Wabash Ave. mariapinto.com
