Most I've seen has been 6in iirc, but DLester could confirm Both size 36 DVN suits I've tried on have had 31" waists with an inch or so to let out. Not sure if this helps, but I hope it does because I knocked over a bag of jelly beans getting that measurement If you call Nordstrom Bellevue at (206) 628-2111 they stock DVN and are pretty helpful if you need measurements your sacrifice will not be in vain. size 50 has a size 34ish waist and was probably 40 inches across the chest, did not bring a tape with me but that is what it seemed like. thanks pals ;o might take a chance on it and see. it's only $6 afterall.
