I'm familiar with the area. I was raised about 30 min out of Orlando in Volusia County and worked at Universal Studios for a short time, so I used to drive past the Mall at Millenia daily. This was at a time that I couldn't be less interested in clothing, so I never took advantage.
Sawgrass is about an hour south of me, so I don't get there frequently, but it's close enough if I'm looking for something specific. I actually just went to Saks Off 5th in West Palm Beach trying to find a (first!) sport coat that fit, and there weren't any "good" brands there. Sawgrass will be the next option.
Feel free to point out any 42R on B&S that would work with an athletic build in a hot climate!
