Finally finished! I had the intention to have them finished before the end of the Lindy Hop season, and they nearly were, except for the hems. For some reason it took about half a year before I had the courage to finally finish the pants - they had to be shortened quite a lot.
And I have to say I felt very, very proud when wearing them. Especially because I paired them with homemade suspenders.
Now I 'only' have to make the knit shirt I intend to wear with it (already bought the fabric, in a color matching the elastic of the suspenders) and the outfit is complete.
Edit (2016): the shirt is also done...see here.
