ok, I was sitting this one out. As a formerly morbidly obese person, there are a few points that I can make
1. I think that, with good bespoke clothing, you can present a very proffetional apperence, even if you are morbidly obese. there are limitations on this - you aren't going to look as good as a fit person with nice clothes, and, more importantly, most people who are morbidly obese shift weight on a regular basis, those fluctuations crate havoc with your fit, so your clothes that fit great one week might not the next. I was going to pull out a few pictures of myself at 330 poounds in a bespoke suit and looking at the pictures I decided I didn't look anywhere near as good as I thought I did.
2. honestly, you shouldn't be so predjidiced against fat people - when I was at my biggest, I probably had more energy to put into my work that 99% of the people here. if a guy gets to be a very effective governor of NJ, he probably has a lot of energy and smarts, regardless of his weight.
3. all that said - a person who is slightly overwieght, or at "normal" weight, will look a hell of a lot better than an obese person is the very best bespoke clothing. such is life.
