I bought some jeans just over a year ago a size smaller than I am in the hope I would fit in them. They were only 3 pounds and I didn't fit into them - could barely get them over my legs, and when I did manage to they were about 5 inches too small across my tummy

More than I expected

But

I am wearing those jeans

and they fit perfectly now

Not tight at all
My other favourate NSV is I now also fit into a lot of my old clothes from 10 years ago (OK they're baggy jumpers I got in early pregnancy but I thought i'd never fit into them again

)
