I chose New Look 6637. The envelope says "Easy 2 hours" and while the construction is easy, it seems to me that the "2 hours" refers to time spent on construction, exclusive of cutting the fabric etc.
Once I had cut out the skirt pieces I decided the fabric was too lightweight - I was worried about transparency - so I underlined it with scraps of poplin from other projects.
All in all the project took me about 7 1/2 hours, but I did stop for meals, laundry etc. I think its the first time I've started and finished a fashion garment in the same day.
I'm quite happy with the finished garment, and will probably make 1 or 2 more for the Aussie summer. Perhaps I'll even make one a tiny bit shorter. I might also alter the side seams to give it a slightly more A-line finish, if I remember.
I am glad I added the underlining, as I think it would have been not only transparent, but a little fly-away without the extra weight.
