I purchased this in 2005 or there abouts. I can only recall wearing it once and is in excellent condition. I was thinner then but I do recall that it held everything in and was firm but not restrictive. It has a kick pleat at the back to make walking easy. It is hard to capture how well these types of dresses fit and how they are cut to flatter. It has 2 stitched bands across the waist and tailoring to the bust which stops the straps from buckling or dropping off the shoulders. It has a side zip closure with a hook and eye.
There is a fair amount to stretch to this dress but please check yourself against the measurements provided.
16" across the waist
18" pit to pit across the back
20" across the hips
39" from shoulder to hem
23" from waist to hem
