It might be shocking to realize that not all body types fit well into a suit, regardless of how well tailored it is. I used to be tall and lanky, great for a suit. Then age happened, and now I'm much more round that beanpole. Nothing fits well, and I've tried custom shirts etc. I just look like a well dressed, round person. I'm not more comfortable at all, in fact the opposite.
Plop me in a pair of shorts with a t-shirt or better, a hoodie and I feel great.
