For work/conferences....
Looking for solid black, 2 buttons (I got a bunch of 3 button ones)....
Hoping to spend around 150 - 250
Where do you getbig millionaires shop? 
If you are looking for a solid black suit with an old fashioned professional look you can get it almost anywhere. At that price range just go the the Men's Warehouse or something.
I've got 1 black suit but I almost never wear it.
I wear grey, tan and brown. Stylin' and pimpin'. Even for work or conferences I don't wear black usually.
But I don;t really know what the popular suit fashions are in Florida. Here in Asia it's really different. Shiny silver is popular. ALso really tight suits and really gay looking shit.
