My husband is usually a waist size 38, and reading reviews it was recommended to order a size larger, so I got him a 40 and they fit fabulous. I can't comment on the inseam, since he's a super shorty (one leg is also shorter than the other) and has all pants custom hemmed. He says they're really comfortable on, and I think they're one of the best fitting and flattering pants he owns now. He's not exactly fit or trim, but these magically make him look slim. They seem perfect for dressy occasions as well as formal work gathering, but since the fabric seems somewhat stretchy they're also great for more casual wear. I bought the black and they don't attract as much dog hair as other pants, and even the hair that does get on it, it's easy to wipe off. Even though it's a poly-blend fabric, they're lightweight and cool feeling. These pants seem like they'll be easy to launder and maintain, and seem like they'll be great for travel and not show wrinkles or stains. Apparently these feel like lounge/comfy pants on, but they look like formal dress pants. Glad I bought them for him, and I'll be on the look out for other colors. Highly highly recommend these pants. I don't think you'll be disappointed (so long as you order a size up). Great fit, feel, and quality, and looks super nice on.
