Never owned Diesels before. I'm a pretty big(not in the good way) guy. The pair of jeans I'm looking at (on eBay that some forum people have said are real) say they are 38x32 low-rise boot cut.

What kind of fit should I expect? I've found "Waist Size 38" to be radically different between designers, and where I live currently there is no Diesel to be found, so trying on really isn't an option. Right now as I sit here I'm wearing a very comfortable pair of Banana Republic Relaxed Fit shorts (38s.)

I don't really want to buy them and have them totally hanging off my ass, or worse, unable to get up past my ass. Any thoughts?

It is hard to say.

Your best bet would be to ask the seller for measurements... waist, thigh, knee, inseam, rise, etc

and compare them to your most comfortable/comparable cut jeans that you own.... Ideally, NOT the BR shorts since they are a totally different type of garment

Are you sure you want to start off w/ Zathan? It's very tight in the thigh and won't feel anything like relaxed BR. The waist is usually loose too so you will definitely need a belt. Together with its low-rise-ness, it is going to be difficult to keep it not sagging on your behind unless you wear them tight.

Have you looked into Zaf and Koffha?

38 would prob be too big, as BR runs more TTS i believe

For the concerned:

I decided not to buy on eBay. When I'm back in Chicago and I can actually try on various fits of various brands, I will then be on the hunt.
