Flared-leg unitard with spaghetti straps that crossed over the open back.
The pattern is compatible with pattern 2800 for zip-front unitards or a strappy skating dress:
2916 pants + 2800 long sleeve +mandarin collar = catsuit
2916 pants + 2800 long sleeve + shirt collar = Elvis costume (think white suit, Vegas years)
2916 pants + 2800 sleeveless + shirt collar = disco jumpsuit
2800 skirt / panties + 2916 bodice = strappy skating dress with side-slit rounded flat skirt
