EOS currently has some luscious mesh knits for sale. I've been waiting for knits like this to be available in order to re-create one of my favorite (and loved to death) RTW tops. Essentially you use a double layer for areas you want more covered and use the second layer for the facing.
1. Use a basic tee-shirt type pattern with regular sleeves (not raglan).
2. cut two front and two back pieces of the pattern from the mesh knit. Cut one set of sleeves.
3. Attach the front piece to back piece on one shoulder for each set (one bodice, one facing piece.)
4. See if you'd rather have right sides together or right side to wrong side for the facing to bodice. Using right side to wrong side (as my rtw top had) allows you to have a pattern on pattern design for your top. This looked fab on my rtw top but may not be what you want depending on your print. Right side to right side will minimize the fabric show through to the front of the garment.
5. after facing the bodice sew the remaining shoulder seam of the garment.
6. Sew sleeves and side seams by what ever method you want.
7. My RTW top was hemmed using a lettuce stitch. This reduces bulk and excessive fabric on this see though knit.
I would think you can use this idea to make a skirt as well. It might be cool to have each layer hemmed at different lengths. If you do this you'd want to use right side to wrong side seaming at the waist so the right side of the bottom layer would show.
