Added a Skirt Lining-How Do I Sew the Zipper?

I am making this dress https://www.flickr.com/photos/motherof5/16120786621/ for my cousin and as the voile is so light I have added a bemsilk skirt lining. The zipper is added after the skirt is attached so what I normally do in this case is treat the lining and main as one, the fabric is light enough that with some gentle pressing it works. Does anyone have a suggestion how I can leave the skirt lining loose when sewing in the zipper and then hand sew it, bearing in mind I was hoping to put the skirt main and lining wrong sides together and attach then to the main bodice, the bodice lining then covering the raw waist edge. Clear as mud? If anyone can make out what I am on about and help, that would be awesome! Thank you! xx N
