I have made another version of this reissued Butterick 1957 dress (my first is on Sew Retro here.)
This time I altered it to put in a back exposed zipper. A clothes store here in the UK has been doing coloured exposed zippers on all their summer dresses (e.g. this one) and I loved the look. I let the waist seams out a tiny bit on this version, to make it more appropriate for comfortable lounging on picnic blankets and the like! The fabric is a beautiful quality cotton lawn.
On to the pictures (and better pictures of the original pink version below!)
