For most of the 36 years that the Hadassah House thrift shop occupied a two-story building just west of the Highland Park Metra station, it was a bargain- and treasure-hunter’s bonanza—chock-a-block with carefully used furniture and high-end clothing (along with housewares, jewelry, what-have-you) from homes in the North Shore suburbs, all at pennies-on-the-dollar prices that were almost always negotiable. But earlier this year Hadassah House moved to new quarters in a Deerfield strip mall, where it now sits between a California Tan and Deerfield Dialysis. Without the familiar crowded rooms and narrow, twisting staircase (lined with artworks), it looks distressingly more like any other retail outlet, but the staff says donations are as strong as ever, and treasures still abound. On the day I stopped by, a party-ready Betsey Johnson frock with a strapless black-velvet bodice and filmy embroidered skirt was on sale for $37.50 in the locked designer room (just ask, they’ll let you in), while a knockout sequined cotton print by Morton Myles from the heady, big-shouldered 1980s was out on the racks for $8. Don’t look for that one; it came home with me along with the blue-and-white Chinese pot ($2) now sprouting ivy on my patio.
