What is you favorite shirt(-brand)?

Brioni.
I find them extremely well made, easy to iron (top-end cotton), excellent design and so on. Plus, you can walk in to the Brioni store in London, get them to measure your upper body, allow you to choose from hundreds of different fabrics, then order semi-bespoke shirts that are made to your size within 6 weeks. Best of all, this semi-bespoke service is only 20% more expensive than the standard off-the-shelf Brioni shirts (as they are all hand-made, so I suppose it's just as 'easy' to make one to your size).
Only snag is there was a minimum order. I can't remember what the minimum semi-bespoke order was exactly, but I think it was either 4 or 6 shirts.
I haven't take advantage of that service (it's bad enough buying one, never mind four Brioni shirts), although I know it exists.
