I know this sounds like it has been asked 1000 times, but after much reading online I still can't find the answer so wondered if you could help?
I see some say you buy 501STF at your normal jeans waist size if you want to wear them without washing at first, and then take a bath with them on after a couple of months, if I understand correctly, but I am struggling with what people mean by normal jeans size
My actual waist measures 29" at the narrowest part, about 32" where I wear my jeans. I normally wear 29W 501s, but when I first put them on, they are tight, say an inch or two gap between the centre of button and buttonhole on the waist, and then they stretch after a couple of weeks wear and end up being just right (ie the waist button ends up lining up precisely with the buttonhole before I button them up). I only wash them when I absolutely have to (roughly 6 monthly) I tend to end up wearing them with my bellybutton 3" above the waistband button and without a belt. I think a bigger size in 501 pre-wash would result in my hoiking them up often .
So, here's the question am I a 30W in 501 pre-washed (but I am sizing down), or am I a 29W in 501 pre-wash?
