I made the prom gowns this year for my twin grand daughters and of course the zippers were invisible zippers. I had not sewns clothes in quite a while, so I forgot that you had to have a special foot. Did not know if I still had the foot and could not find it. We live about one hour one way from a store, so I improvised and yes, you can put an invisible zipper in without the foot. Don't ask how it goes, but seeing this picture, I know, I have that foot somewhere. p.s. The gowns came out beautiful.
