I find this pattern superb for anyone who is bigger around the bum/hips than they are at the top. It saves having to blend sizes if you want a normal fitting top. I have a huge 5 size difference between bust/waist measurement and hips measurement and most normal patterns just aren't designed for that amount of difference. With the fit/flare design of the Iris, I can make a t-shirt that fits like a regular t-shirt without having to blend sizes at all. I can use the measurements for my bust/waist and because of the extra width at the bottom it fits perfectly
