At 6'3" and 200-205, I have had good luck with the World Jersey's Large size. Length is okay, but I tend to make sure I have something in the jersey pockets to keep them pulled down. Without any weight in them, they will ride up a bit, but keeping my spare tube and CO2 in there as a minimum, no problem.
And I use inexpensive Pearl Izumi Quest shorts, after wrestling Specialized bibs that are either too loose in the leg or too tight in the straps, and have never had an issue with them.
