I was actually more impressed by the fit of the suit; only one in the pic with zero collar gaping. Is that TF? The wider lapels and large ticket pocket flap look like his.
Oh, and regarding the shirt, there are a lot of reasons it may look so neat; it fits perfectly, it's new, it was recently hand-pressed and so on. Shirts that don't fit quite right will often have messed up looking collars. Oh, and it's impossible to tell whether the shirt is actually completely opaque; if one wears an undershirt under a white shirt you can't tell unless they remove their jacket.
