At my highest weight of 210 I was an 18 on top and bottoms, but I pretty much lived in stretch jeans and cheap, plain tops from Primark, so I'm sure something tailored would have had to be bigger. I had a pair of size 16 trousers from BHS that I pretty much exclusively wore to work, alongside a size 18 from new look that were just way too big.
Now I'm hovering around 190 and I can wear a size 16 in jeans with or without stretch, although without stretch are still tight around the tops of the thighs (I have chunky legs and a big round bum) and I have to invent new ways to cover up the muffin top, but hopefully not for long!
I also had a breakthrough in Primark yesterday, where I fit into a size 14 jacket! My shoulders are much smaller now, but my belly is still pretty big so doing up the button is a no no, but again, not for long
I'm excited to fit into a 14 properly again in bottoms especially!
