Maybe even water off a duck's bag.
Good to see that you've got a full stick, Fox!
I've got a full-stick Maglia umbrella that I got from Rene at Deer Style here in Brisbane, which is very nice.
If you don't mind ordering from Howard Yount (where the service/communication is non-existent, but the actual goods are very decent), you could get an Italian full-stick umbrella for US$165 + shipping:
Sup? What's your budget like?
I mean there's Ueki at Ciccio. About AUD 5,000 for a sportscoat.
If you're ever in Hong Kong - or if you can get them to deliver, Leung So Kee's whangee handle umbrellas are about $60. Comes with a lifetime warranty for repair (broken/bent spokes, etc.) They've been making umbrellas since 1885. On an island that regularly experiences typhoons. You're probably in good hands.
Their website is down now, unfortunately. Try back in a few days, I reckon.
Gerry and FXH will hopefully be able to provide more info on Tailor Caid. I haven't been there so I'm afraid that I can't comment but the photos that I see on the internet look nice, particularly if you like Ivy/Trad style tailoring.
The two tailors in Tokyo that I've heard most about are Ginza Tailor and Azabu Tailor.
Ginza Tailor does bespoke, whereas Azabu Tailor does MTM, using a pattern which they adjust to suit your needs, based on an existing block. AT is very affordable, whereas Ginza Tailor is more costly.
I don't know whether people in either GT or AT speak English, so it might be difficult to order something, but it could be worth trying.
Ginza Tailor (or "Gintei", as they're colloquially known): http://www.gintei.com/
Azabu Tailor: http://www.azabutailor.com/order/
As an aside, I believe that Kazuna in Sydney used to work for Azabu Tailor.
Oscar Hunt are now open in Sydney!
They're at LVL 2/73 York Street, and contactable on 02 8097 2470. The rest of their details can be found on their site.
They also have a bit of a competition on at the moment, they're giving away two MTM suits, one for Sydney and one for Melbourne, details can be found here.
