So my inside is 32" what length do I get no1 trousers , I believe they are supposed to be a bit short
You should be ordering length ‘85’ trousers and turn them up about an inch and a half, they should not be short as you put it, but should break on the laces of your shoes.
Yep, order long, and go to a tailor.
The bottom of the front crease should be at the second eyelet on the shoe I think. And ask your tailor to do Cavalry Cut, which drops the hem down at the back rather than running it parallel. In my opinion, don’t go by QCS, they always look as though their trousers are too short.
