I had this one piece Culotte Skirt made from the orginal Simplicity pattern shown below by a lovely dressmaker last year .
Simplicity 1209; ©1955; Misses' and Women's One-Piece Culotte in Two Lengths and Culotte Skirt: Bias underarm insert insures smooth fit and freedom of action. Views 1 and 2 have a convertible collar and button front closing. There are slits at lower edge of short kimono sleeves. Short version is shown in view 2.
And this is me wearing it on my
recent cruise to North Africa
This One-Piece Culotte is really very comfortable and can be dressed up or down, I think I will have another one made in Gingham, as shown in the pattern picture.
