Lucky moment: I found this PERFECT fabric and it was on sale! ^_^ It was Fake Suede which I used for the yellow part of the jacket.
Easiest part: There wasn´t many easy parts. But sewing on the black part on the bottoms were easy.
Hardest part: Me and the seamstress sew the black part on the front wrong, so we had to pull the whole jacket through a small hole. It was also veeeery hard to sew, restistance non-stop!
