[MR] OT Corset question

[TinkerbellProxy at aol.com]

I was wondering if anyone had a site or retailer of functioning corsets  
they could recommend.  I keep finding places that advertise corsets but  when 
I read the descriptions, they are not truly functional but just  decorative. 
 Or extremely expensive.  So I guess I'm also looking for  some where 
that's reasonably priced as well.  I have a wedding coming up  that I'll need a 
plus sized corset for.  
 
Any help would be greatly appreciated.
