Slowly, Slowly

This dress has been coming together. It's looking a bit like a tent (yes I did measure myself before, thank you very much), but I don't want to rip the side seams out and start over now that the collar is gathered and stitched in. It will probably still be cute with my favorite vintage
Frye bootsor some tights and ballet flats.

I bought an invisible zipper, and I am procrastinating on putting it in . . . zippers scare me. Any tips from sewers out there?

I want to wear it in time for the holiday shows I'm doing.
