Elastic casing idea

Working through Vogue 8390 and making changes as I go. The pattern calls for two right front pieces and two left front pieces, sew each right sides together, turn, topstitch 1/4 inch from edge. This is exactly what I should have done on my bat wing top!

The back is one piece only.

I basted the entire top together and tried it on and felt thick through the middle. This fabric is interlock so too thick for doubling up... I decided to cut a lining out of 70 denier poly which is lighter and so soft. I might add I sacrificed a future planned project to do this. Ah, well.

Still, it felt too thick through the waist. I picked out the basting and halved the lining so just the upper bodice remained... basted it all again and felt much thinner through the waist. Maybe I'm not used to gathers, but I definitely don't need more fluff through the middle.

Next problem. The back seemed too thin as one layer and just not right. Back to the cutting table to cut another back piece out of the 70 denier. As I was cutting it occurred to me that I could sandwich the elastic between the fashion fabric and lining, thereby creating the casing for the elastic without turning down the upper edge as the pattern describes.

I stitched right sides together 1/2 inch S/A, pressed, turned, pressed, topstitched 1/4 from the edge, slipped elastic inbetween and topstitched from the right side as close to the elastic as I dared to go. I am so happy it worked!

I'm looking at it and wondering if I should insert elastic on the front bodice pieces or not. Any opinions before I seam up the sides? It should be okay but maybe someone has advice before I get brave and finish it tomorrow :)
