This is Simplicity 6388, a 70s sunfrock pattern, with a slim skirt instead of the swishy full skirt. Thank you Moggy, for giving me the pattern and I hope you are continuing to buy patterns in my size at opshops, so I can rifle through your drawers again this Christmas. (ooo er!)
I didn't do the crossed straps at the back. I prefer to wear a plain old regular bra, not a convertible or strapless. I also made another top, the cowly sleeveless New Look 6470, in a rayon knit.
