Hi again, I'd like to help out by explaining a few things:
SIZING: I haven't tried the Weird Guy fit, but I own a pair of Skinny Guy fit heavyweight jeans, and compared to these they seem a little bit roomier in the thighs and with a slightly higher rise. So you don't wear these jeans on the hip but on the waist and your crotch has some room.
FITTING: Denim stretches... a lot!!! My midweight selvedge jeans have stretched 2 inches per side (4 inches overall) in the waist, give it or take. So if you buy a pair that is 30" at raw/new condition, expect to stretch out up to 34" after fully broken in.
These N&F jeans are a nice 3-season midweight 13.75 oz., so expect to be broken in after a few weeks and fully broken in after 2 months of hard wear, depending on your lifestyle, rotation and other factors.
BELT OR NO BELT?: If you want to avoid belt at all cost, that's pretty much imposible because of the stretching out. But in this case, you must buy your jeans very tight - I mean "uncomfortable" tight. You'll suffer about 2 months but when fully broken in you will be in bliss because they will have molded to your body... You won't want to wear anything else.
If you want jeans to be comfortable since day 1, then size up, but they won't feel as molded to your body as the tight choice. If you buy heavyweight jeans, don't try the tight choice... Your balls will thank you.
RAW JEANS: "Raw" means "water-virgin", no wash whatsoever except for sanforization, and they should be stiff (such as the classic "Shrink-To-Fit" 501 Levi's). The stiffness feels weird if you're not into raw denim, but you get used to it and the fabric will eventually stretch out and soften with wear and your own sweat. Raw is better if you want high contrasting fades, because the creases set in better when the fabric is stiff.
SANFORIZATION: I understand this first drop is with sanforized jeans - Unsanforized jeans can be very tricky for sizing when you don't know much about jeans, because they shrink a lot. If you buy unsanforized, a pre-soak is mandatory, or else you will have your honeycombs behind your things instead of your knees... And that's weird.
WASHING: Raw jeans are recommended to avoid washing as much as possible. I agree, but you must wash your jeans sometime!!! Not washing at all will make your jeans beautiful, but they'll probably smell, and last less because cotton fibres will become brittle. So my advice is to wear your jeans hard as long as possible and avoid washing them, especially in the beginning, when the jeans are the bluest, and wash them more often when the creases are settled in and the dye is less dark blue.
I recommend washing your jeans by hand in lukewarm water, inside out and using a mild soap (I've been using a soap for dark clothes). It' easy, it takes 1 hour of your precious time at best and you make some exercise... Actually you agitate them a little bit and that's all. Dry them inside out in open air. Jeans will shrink more in hot water and less in cold water, but they will eventually stretch out again to the broken in fit. If you love your jeans, do yourself a favour and avoid the washing machine and especially the dryer at all cost.
If you want to know more, there are a bunch of nice blogs and websites, such as Heddels.
