My Husband is 6 foot 5 and always has trouble finding pants that are long enough for him. Bigtalldirect is a reliable site to buy clothes that actually fit him well. They usually have everything I order in stock. You get 10% off the first order so I would recommend taking advantage of that offer.
I've ordered a number of products from the website over the years. Invariably, everything fits as advertised, and the color is as shown. This is a plus. Also, very competitive prices and good customer service. And, stylish clothes for fat men. Also a plus.
Have ordered shirts, pants, and even a suit over the past 10 years, or so. Always a good experience.
