Let's point out how many things we see wrong with this picture: the hem hits at a length that makes me shorter than I am (something I always have to watch since I'm nugget sized), the dresses' cinched waist is not sitting correctly to look cinched but sort of billowy, and overall the dress is too big (another thing of mine is to buy an item oversized and rework it but that is for another day).
So what did I do, I added a huge men's belt and I hiked that sucker up above my knees. Problem solved.
It works perfectly, if I may say so myself. Here's why: the dresses' own cinched waist acts as its own belt for keeping the extra inches inside the dress itself and off the length. I would assume this is a universal tip for any dress built the same way with a length problem. Cheers to making it work.
