The whole suit is lined with a super nice, thick white swim fabric. I got a remnant of it at Joann's for $4, normally $25/yd. It made me realize how thin the green fabric is (basically see-through if unlined). Do you see the beautiful finish done by the cover-stitch? I love it!
This is how nice it looks on the inside: just like store-bought.
The only problem I had was the application of elastic. I did the legs first, figuring they would show less. I followed the pattern directions and cut the elastic at 90% of the leg opening. That was too much and as you can see in the top picture, it is not very gathered. For the arms/neck, I just pulled it as I stitched. That worked OK, but it is somewhat uneven. I will have to practice more.
The suit fits, but it is a bit short and pulls in the back. Still, a good first try. Next I might try the 1-piece "wetsuit" type swimwear for Andy or a cutie girl suit for Ella.
