Finished top

I have finished this test top ( muslin ).

This top has elastic at the sides, I anchored the elastic at both ends first, then stretched it and sewed it on to the seam with a tricot zig zag stich. The front of the top is crossover so the front has a double layer of stretch fabric to deal with. I used a lightweight iron on interfacing an inch wide at the hemline which made the hems easier to sew without stretching, I also did this at the sleeve hems.
