When I decided to rent this dress, I'll be honest that I didn't look at the back. When it arrived I was definitely surprised to see the little cutout and thought, "maybe I should just send it back immediately without wearing it?" - but I ended up wearing it to my office on a regular day (albeit extremely muggy) with a cardigan covering my back - problem solved. The real problem was that despite my peanut sized head, I had difficulty fitting it through the head hole. Like, I thought I was going to have to ask for help to get the dress off - that kind of difficulty. Probably would not rent again, sorry!
