This is an evening gown cut from a 1930’s slip pattern.

This is the original 1932 McCall pattern front.

I cut the low back View 'A' from transparent satin on the true bias instead of on the straight of grain.

I lined it with a muted purple tone of iridescent silk chiffon and created the bottom flounce in another purple shade of silk chiffon to match the prevailing color of the transparent satin.
