I have done a couple of alterations on my Shirtwaist dress, and now it looks much better.

I removed the yoke and took the elastic off of it, I then replaced it using the old fashioned method (two rows of stitching and gathered it by hand)

After removing the sleeves and undoing the under arm seam, I redid the seam with a 3/8 inch seam instead of the 5/8 seam which gave me an extra 1/2 inch.

Using the pattern from my New york 444 pattern I have increased the arm sync on the front, I also redid the under arm seam by the same amount as the sleeve.

After trying it back in the armhole, it was still too puffy so I removed a couple of millimetres from the entire top of the sleeve head going from the single notch to the double notch.

The sleeves are now in the dress and although are slightly puffy they look miles better also, for some reason the fit overall looks a lot better
