@rickyrickygrimes - I probably have a 'normal' sized/shaped body (whatever that is), but my measurements for bust/waist/hip never put me at a straight size (ie - if I was making a dress or jumpsuit where all 3 measurements were needed, I wouldn't be the same size in all of them - my bust would be one size, my hips the next size up and my waist the next again). Sometimes I grade between sizes, but mainly I choose the size that is closest to where it's most important that the pattern fits, and take it from there. I tend to like things reasonably fitted around the waist, so can get away with a smaller size there anyway.
What I have done is found pattern companies that I know fit me pretty well, and they're my go-to for new patterns. In my case, I've yet to find a Closet Core pattern that doesn't fit me, so I've made a lot of their stuff (and I love the designs too), but also Fibremood fit me well and have plenty of options. Grading between sizes is pretty straightforward though, as is altering seam allowances to fit.
@Cantalever - there are lots of places to buy lovely fabric online. Fabric Godmother does a lot of deadstock, as does Rainbow Fabrics. Also Sew Me Sunshine. Guthrie & Ghani do lovely fabric - not so much deadstock, but really good quality stuff that is lovely to sew and wear. Not the cheapest, but always washes and wears well and is therefore good value. Plus they sell in 0.1m increments so you don't need to over-buy.
I make all my own clothes, and haven't bought a thing (apart from socks, knickers and bras) since 2019. I didn't set out to do that, but I have got to the point where I think I'd give anything a go. I've done jeans (several pairs - my favourite thing to make), shirts/blouses, t shirts, jumpers, tops, dresses, skirts, jumpsuits, jackets, pyjamas, coats... it's totally changed the way I dress. I am wearing things that I never would have looked at in a shop, and loving it. I do wonder whether I will ever buy clothes again. I really need some new running gear, but I have a book with 'activewear' patterns in it, so I think I'll tackle that next.
