    I looked high and low for a suit that would fit without breaking the bank. This suit is really comfortable and let's a portly guy like me move with ease. Would for sure buy again.

    This suit is very well made and the wearer found it to run large. We had to send it back for one size smaller. It appears to be top notch!!
