dickies are tight, but its hard to find good fitting ones nowadays. i cant find the slim straights anywhere but online and the new 874s are baggy as fuck.
I feel out of the loop, didn't realize they made any styles other than regular and the baggy 5 pockets. Pretty much all of my dickies are 5 to 15 years old and still going strong.
I've always said that with any dickies you should go to your local army surplus or work clothing outlet, take 5 pairs of the same size and color and try them all on. They're inconsistent but when you find a good pair they're awesome. I have well fitting 34x34s and I have baggier 33x32s. No slim fit or loose fit or any number style, all just plain original Dickies.
Also, if you want a good durable pant similar to Dickies but with modern features like buttons, looped that fit a normal belt, and pockets that don't dump out every time you sit down, try Ben Davis. Same comment about inconsistent fit (not as bad) and with both plan for slight shrinkage and a couple washes with some fabric softener softener to help with the initial starchiness.
