Bike jersey/tri jersey and tri suit fitting

Want to take advantage of a few deals on the internet, but new to the sport and have no experience with bike jerseys or Tri-suits or tri-tops. I know that different brands fit different, but any idea on sizes?

I'm 6'3", 205 lbs, 36 waist. I have tried bike shorts and large fits good (pearl and LG). I am leaning for large jerseys also (both cycling and tri), does that sound about right? Brands that I am looking at are Pearl, Zoot, 2XU, and LG.

tri-suits have me confused. they ask for waist and chest, but do not ask for height. The couple of tri-suits that I m looking at are Zoot and Saucony (knew they made good shoes, any experience with their clothing?).

Hoping that someone with similar build reads this and tells me what works for them.
