What's got a slimmer fit, a slim bootcut or a slim straight cut? I'm debating on whether or not to purchase this RRL jeans that's tagged 30x34. The waist is measured 32" and the inseam about 35". The waist is good, but I'm 5'7" so I'm going to have to hem at least 3-4" off the inseam. The guy selling it advised me that it wouldn't be a bootcut fit anymore, but a straight fit because I would have hemmed the flare. I think I'm just gonna do that because I want some RRL jeans damnit lol.
The term "slim" is used rather loosely in general when it comes to jeans, and it really depends on the brand and model of the jean in terms of whether a slim boot cut or slim straight cut is slimmer. Unfortunately, as far as RRL goes specifically, I don't know which one is slimmer.
Also, IME, I would disagree with the sales guy you talked to about losing the flare when you hem. Most men's boot cut jeans start flaring out from the knee down, so even if you hem, you'll still get some flare unless you hem all the way up to the knee.
