Trying to find my size

So I urgently need to buy new pants, I went to the store yesterday and I had never had such an experience. Apparently I don't fit in the largest size at some stores...

And so I really thought I was a large but I'm really an extra large🤣.

I find it difficult to fit pants anyway and especially with my belly these days. I always look for straight or wide leg pants but as you can see I really struggled to get the pants on because the pants are still tight on my thighs.

I thought let me try on a dress but looked a little pregnant in it😅
