Designer Mona Kowalska has owned and operated her boutique and clothing line, A Détacher, since 1998. Originally from Krakow, Poland, Kowalska cut her teeth designing for a number of Italian labels as well as running the studio for Sonia Rykiel. Over the last few years, we've seen a number of our favorite boutiques like Creatures of Comfort, Assembly New York and Totokaelo add her whimsically-proportioned, expertly-colored and patterned pieces and singular style to their already stellar offerings. We got to chat with Kowalska, who seemed remarkably calm before the presentation of her F/W 2012 collection.
