Michelle Costello, owner, Una Bella, Chicago

Where she shops: “New York and Chicago.”

Secret finds: “Knit lines in Sandra Soba’s showroom like Dolce Emozione, Penny Wallace and Babette.”

Tried-and-true lines:

“Louben, Bill Burns, Renfrew, Ann Freedberg and R’ae Angelo, a Chicago designer who handpicks European fabrics.

Current bestsellers: “I can’t keep in a Persian lamb coat in full or three-quarter lengths.” Favorite showrooms: “Studio Elle, Karin Berger, Bernice Burg, Sandra Soba, Boe Chmil and Bruce Brown.”

Biggest challenge at the Chicago Apparel Center: “The showroom set-up isn’t as easy as StyleMax’s. I prefer booths because I can see and discover more lines.”
