I wore a Bonobos suit in my wedding and had a great experience with them. They have "Guide Shops" in many major cities[1] where you can go try on the clothes, talk to the sales associates and browse their collection in person. After your ~30 min appointment is over, they email you a size reminder for everything you tried on (so you know that your suit top should be a 40R slim and your pants should be 32 straight cut and that you wear a slightly different size in their business shirts as compared to their casual ones or whatever). 20% off the first order as well meant I paid a very reasonable amount for a well-fitting suit that I was confident would fit without excessive tailoring. The other options I was looking at either had poor-quality fabrics / seams, fit poorly, or were more expensive. [1] - https://bonobos.com/guideshop https://bonobos.com/guideshop
