On a recent trip to Calgary, I had the pleasure of visiting a truly different consignment clothing store called Vespucci.
It's different because:
 Sheer size -- most consignment stores are tiny. This place is huge. It has it's own building.
 Quality, not just quantity -- I didn't see anything junky. There is a sense of a curatorial approach here, where the owner is bringing an aesthetic to the collection, not just taking what is out there
 Range of prices -- there aren't many places you can buy a Feraud suit that's gently used. But you can here. I also picked up a nearly new denim jacket for $10.
 Great staff. When I started snapping pics with my Blackberry, the owner suggested I check out the view from the balcony. And encouraged me to check out the formal wear while I was up there. Now that's friendly.
This is a store that gives you the thrill of the hunt, like a Winners does, but with much better quality clothing, for the most part.
You can bring a great customer experience to practically anything with some thought and attention.
The waiting area. Chairs match the overall aesthetic.
Main floor view. Fabulous building with skylights adds sense of luxury.
Every category has room to develop an interesting and differentiating experience. Although the owners were concerned about having expanded during a recession, I expect they will do quite well with their approach.
Thanks to Adam Lawrence of WorkPlayExperience Blog who let me know that "consignment store" is an unfamiliar term outside North America. A consignment store is a store that sells new or gently used second-hand clothing on behalf of the seller, in return for a commission. Some such stores may actually purchase selected items for their inventory, but most is sold on a contingency basis. In the UK, such a store might be called a "dress agency." Thanks Adam! Much appreciated!
