Isn't it one of the most important things on a rainy day, that your outfit makes you feel good?
I got lucky one day and inherited an old pair of jeans from my man. It had ugly oil stains, so luckily I didn't even get tempted to wear them as boyfriend jeans. There also was a funky piece of jean fabric in my stash (from a skirt I once made considerably shorter):
I used my basic front bodice pattern for the general shape. Instead of darts, I made the upper pattern piece (above the under bust seam) wider than the lower one. Makes sense? By the way, there is a great basic bodice pattern on the BurdaStyle site, for free! Here: basic-bodice-pattern . I made my own, using my personal measurements, but I bet the Burda bodice would be a good start.
Besides, if you look (too) closely, you will notice the stress folds in the back, so my fit isn't perfect. After making my personal basic bodice pattern, I didn't think I needed a muslin. Lesson learned! So why is it that I believe I might make the same mistake again next time? Sheesh...
I didn't have a zipper on hand, so I used the snap buttons on the left side instead - I really wanted to use what I had at home, otherwise I wouldn't have come up with this idea. Lovely though, right? Now I have a new top for zero money, yay! Of course I also had to use one of the original pockets, even though it might not be all that practical.
Ok, I admit - I still prefer non-rainy weather.
