DOn't have a waist cincher as such, but do have a full on corset...like this www.figleaves.com/uk/product.asp?product_id=VOL-V4000U&mci=&size=&colour=&image=pcm_vol-v4000u_black
is absolutely brilliant, but not really the kind of thing i'd wear every day. Once it's done up properly, you may have lost 3 inches of your waist, but bending over becomes something of a challenge! I come over all 19th century in my deportment!
I must admit I've been considering a more flexible waist cincher, so will watch replies to this with interest...
