I’m a little bit taller than you but always had a small waist and although the weight came off pretty quickly while I was bf I did retain a last couple of inches specifically on my waist which came off when I weaned. I hope that’s reassuring.
I had a rather nice skirt which I wore during the intermediate 6 months and as soon as I quit bf it was suddenly too big around the waist. I still miss that skirt but it was the wrong shape to get taken in - but I passed it on to a more rectangular mate who looked great in it
