I finally managed to do some sewing for myself, making the top above from some quilting fabric. The pattern, a Built by Wendy, is extremely simple, and as I was sewing it it occurred to me that it would be easily converted into a maternity top - no, not for myself, but for someone I know who's expecting.
So I simply added more length in the front and gathered the sides so it was even with the back. I made it in a stretch fabric to give even more room.
It's a bit hard to photograph yourself modelling clothes, and even harder modelling maternity clothes when you're not pregnant, but here's my best attempt.
