Vienna is a great place for second-hand and consignment shopping!
Thrift stores are clean (ish), well-organized, and attract all kinds of shoppers. Look for bargains in glassware, china, enamelware, linens, and hand-painted kitsch of all kinds. Toys and sporting goods in good condition are also easy to find, as well as “extra” furniture for your US government housing, such as inexpensive bookshelves, desks, or wardrobes.
Caritas, the Catholic charity, has two large stores in Vienna with pretty much everything from housewares to clothing. A special section in each store features antiques. Check out the larger store on Steinheilgasse in the 21st district for the best selection. Donations are also accepted at the store.
Humana stores specialize in clothing. There is a good selection of everything from pajamas to fur coats. The store on Wiedner Haupstrasse in the 4th district features a large trachten (traditional Tyrolean: think lederhosen and dirndls) boutique with clothing for men, women, and children.
The Vienna city animal shelter (Tierschutzheim) has a very nice fundraising thrift shop. It is not easy to find, but this shop has a great selection of antiques, especially books and linens. Open only on Sundays.
Consignment stores are also very popular, especially for “dressy” or vintage clothes, including ball gowns and trachten. With all the balls held here in Vienna, turnover in ball clothing and accessories is high, and great bargains can be had. Find out more about consignment and second-hand shops here.
