Austin is shorter and the pants are slimmer
Daniel and Nigel are both less padded (vs. Anthony), don't remember what's the exact difference between Daniel and Nigel though I like both more so than Anthony these days
Nigel has a softer shoulder than the Anthony Cut & is half-lined or unlined. Conversely, Anthony is has a stronger shoulder. Thats atleast my experience. Both nice, and both drop 7. The Anthony will give you more room in the shoulders, & approximately the same in the waist. 44R Anthony fits me well, I had to size up to 46R in Nigel, but take in the body.
Its not C&J - it is made in Italy. I have those loafers in navy, burgundy & the polo suede you posted above. I am not sure who makes them, but I can say I like them: they're comfortable. They, however, are blake welted, which may or may not be an issue for you. Definitely not C&J
Well, it has happened. You can now buy a Ralph Lauren Purple Label suit for a cheaper price than Brooks Brothers (Golden Fleece). I suspect they will keep their Drake suits (more expensive). The Anthony looks like its lifted straight from Black Label. If I were you, I would wait to get your Anthony suit with a nice little purple label "RL" tag on the inside.
