Lynette in her ballpark dress. More photos here. It was a really cool design. It looks like an apron or something laid out, or really a big piece of fabric with a hole in the middle. You put your head through the hole, pin the sides of the front behind you in the back, then take the sides of the back half and pin/ button them in front.
The end result is a full circle top-skirt, and what looks like a pencil skirt underneath.
Lynette is too modest I think and doesn't give justice bragging about her designs, so as the older sister I am really proud and impressed so I am bragging about her instead.
