Sorry for the double post, but my friend and I live in the PDX area and she gets her corsets from the local stores such as Spartacus and Static.
Ordering online can be frustrating as you won't get to try on the corset until it arrives, and if it doesn't fit, shipping costs if you have to send it back for another one.
Check out your local stores... I'm sure there's a place or two in your area that you can go to.
