Not a fan, personally. Perhaps I've seen too many cheap/bad examples, and that's coloured my perception of the style. But I feel's there's something mish-mashy about the style. Brogued lace-up boots, sure; can look fantastic. But brogued chelseas... eh, just not for me. I didn't realise "dealer boot" was the name for this style; I thought it was just another synonym for chelseas generally. Learn something new every day!
I learned that distinction online, so it's suspect. I'm convinced there's a nice pair out there, but I keep seeing terrible ones. The nicest I've seen were at Paul Stuart, and were an incredibly refined version -- chiseled last, super fine broguing, brown suede. You could hardly tell they weren't plain toes.
McBindle: the DFIH might be a bit big for that collar, which has a little less roll than my ideal. When I wear a shirt whose BD collar strikes me as a little short with a tie, I often reach for a knit (skinniest ties I own). The ground of the tie is a bit too similar to the jacket. IMHO, with a navy blazer, medium gray trousers > charcoal almost all of the time. I'm not as adamant about full-lengths as some (though I include them whenever possible), but a little more distance between camera and fit would help.
EDIT: Canta, is that a hopsack suit? The textures there are amazing.
