Description from Knitty.com:
This nightie combines the advantages of knitted and woven fabrics (stretchy and see-through, respectively), to show off your arms, shoulders, back and chest, while skimming over those other bits you might not be as crazy about (ahem, not to mention any names, Waist and Hips).
The ribbon trim assures that nothing gaps, and can be adjusted for a custom fit. If you choose 45-inch wide fabric, the length can be anywhere from short to ankle length.
For a closed front, replace the ribbon in the band with quarter-inch elastic, sew the ends of the fabric together, and position the seam in the back.
