Celebrity stylist Kate Young, who counts Michelle Williams and Maggie Gyllenhaal as loyal clients, is launching a collaboration with Target to offer a brand new line of womenswear.

Just in time for prom, one of the key highlights of this ultra-affordable collection is the number of evening options available. Appropriately, Target threw an over the top prom-style bash, complete with a disco ball, couples modeling the evening looks, and mini champagne bottles to celebrate the launch of Kate's collection.

I just started working with Kate Young as a stylist, but I've noticed already that her personal style is really down to earth. - Maggie Gyllenhaal


After chatting with Kate, who describes her style as "edgy classic" on the red carpet, StyleList found out her favorite look from the line was the one she just so happened to be sporting - a little black number with a sheer, polka-dotted top - perfect for prom, or night on the town!
