I just got a few and have to say the fit is great. They are long and slim, which is unlike other brands which seem to think that slim people need shorter shirts for some stupid reason.
polo slim fit might get you close
Yeah...I don't think I'm actually a drop 2! I can easily get a finger or two between the waistband and my stomach (not sure if that is the right "test" but it seems about right) in the size 30 trousers. Perhaps I am just not used to such a slim cut. This is my first foray out of the world of Men's Wearhouse.
XXL. Shouldn't be that bad in the waist,
I wear a 16 1/2 slim fit/extra slim fit dress shirt, 42 regular in a jacket also with 19" shoulders, 44 chest. I bought a large in Kent's polo and it fits just a bit snug after washing. An XL would be ideal. Also note that the sleeves are a bit shorter and should fit you fine.
