I've been after a pair of these for a while and finally bought some. I wasn't sure on size as I wear a 12 but they come in waist/leg sizes so I googled and apparently a 12 is a 31 inch waist. They've arrived and are massive so have to go back
. I'm a 12 in most things but more 10-12 than 12-14. Any idea what size 501s I need to order? I have no tape measure handy. Thank you,
