Quality at affordable prices.
Size: 11.5, Color: British Tan/Ivory
Best old guy shoes. They look great and have support for feet. You don't want cheap department shoes. You will pay for that in your later years.

Nice Sport Coat
Color: Light Blue, Size: XX-Large
May run a little small. I wear a large, my sport coat is a 44L I'm tall, no belly. Ordered the large knowing the arms would be a little short, jacket did not fit lacked 4" of coming together at button, returned. (Amazon is easy & great to do business with) Ordered the XL that was a keeper. I like the lighter material for warmer weather, evenings, etc., the color was accurate. Just what I was looking for.
