I didn't cut out the skirt portion. I did extend the top by about 7", as well as extend the pleat.
One thing I should have done is add a little extra to the arms since my upper arms are a bit thick, but it will work. Luckily, I used some spare suiting polyester for the shirt, so it has a little stretch to it due to the weave - not due to a percentage of elastane or spandex.
The best things about this top is that I can reach overhead with out stressing the fabric, it's comfortable, and busty people can fit into this. If you know a thing or two about sewing, it wouldn't be hard to alter this pattern for the bustier woman.
