I unfortunately don’t have any pictures of the dress being worn, but I don’t think you really need one to see what it would look like. But if I do get a pic, I’ll put it up here. I’m just going to show first, how I shortened the sleeves of a cuffed long sleeve. The cuff came in handy but isn’t really necessary since you can make your own piece. I’ll explain later.
Start by cutting the sleeves to the length you want them, plus about an inch and a half and then hem it.
Take out these stitches
Cut close to the edge along the lines (see picture) and take off the button
It should be a long strip like this with creases. If your shirt either has no cuff or is not like mine, you can make a strip of fabric and make it into a point at the top quite easily using leftover sleeve.
Fold along creases as shown
Top stitch around the edges
Make a buttonhole at the top, below the point.
Fold up the hem of the sleeve 1/2 inch two times
Tack four or so times around the inside not going through the top layer so that it will be invisible on the outside.
Find the center top of the sleeve and pin the placket on the inside, with the point out and wrong side facing up and inside end just 1/4 inch back from the folded hem as shown.
Stitch and attach button.
Button it and repeat for the other sleeve and your done! And save the sleeves if you haven’t used them for the placket because they can be used! On the skirt slit.
Cut the sleeve open and cut the cuff off.
Hem the bottom and gather the top
Pin the insert starting from the bottom up. There is a reason for going from the bottom up.
The reason for going bottom up is because it might not be the same length as the slit. If that’s how it is, stitch the insert in along the original stitching line as the slit
Slip stitch the opening closed to about 1/4 inch below the top of the insert. Take a few stitches back and forth for strength.
On the inside, pull up the gathering stitches tight.
On the outside, stitch. Finish edges and you are done. Repeat on the other slit if there is one :) and enjoy
