FIND YOUR SIZE
The trousers have a relaxed fit, positioned at lower waist, so use your (lower) waist and seat measurement for sizing.
If you wish to adjust the relaxed waist you can choose to add more or less elastic tape. Just remember that the waist has to be wide enough to be pulled over your seat when putting the trousers on.
You can easily shorten or lengthen the pattern, make the adjustment at knee height.

Almost long trousers
I have been searching for a good trouser pattern and now I have found it! The trousers fit well and it is easy to sew. I certainly will make more trousers using this pattern.

Just fabulous
Love these trousers! So comfortable and can be adapted to most looks. This is the first waistband I have done like this, but after a couple of read throughs it worked perfectly.




Favorite pant pattern - I love them!
I made three pairs in the same stretchy Tencel Twill fabric. I am size Eu 46/48 in pants and my height is 174 cm. According to my measurements my first pair was in XL and I remember I had trouble with the waistband, which was way to big. I ended up cutting off the waistband and removed a couple of cm, but overall they were still far to big, and too short fir my liking. My next pair was in size L. They were close to perfect. Only alteration I added 7 cm to the length to get the “ slightly above the ankle” look. I was so pleased with the result, and the comfy, perfect fit, that i made a third pair in the same fabric, but in a different color. The instructions were easy to follow. The waistband being the most challenging part me, but still manageable. I used high quality stretchy Tencel Twill, which is the perfect fabric I think. Definitely have to try stretch- denim too! Someday I will try with non-stretch fabric, but for now I am good with 2 perfectly fitting pants. Never thought I would say that! Thumps up, with this very great pattern! I am very happy!
