Tweedy, those combos are, without exception, impeccable. Hard to pick a favourite, but I guess nos. 2, 5 and 7 are the stand-outs for me. I particularly notice the way you introduce a new colour to each palette via the pocket square, thus providing a subtle off-centre highlight. Also your shirt collars are always on point (as it were). Hopefully other contributors can match this standard, in which case this will undoubtedly become a reference thread for next-level element matching.
