1970s seafoam green tricot nightgown with keyhole cutout and x back.  Could be worn as a dress with the correct undergarments but it is not entirely opaque. Very nice condition with minor wear.  No holes that I noted, straps have minor stretching. Marked a size 7 which is an xs, will fit a small as well as tricot is stretchy.  
Bust: 30" flat, will fit larger, up to about a 34" or possibly larger with less coverage

Waist (no seam, at narrowest part): 29"
Hip: 32" flat but will fit up to about a 36"
Length: 53"
