Le Noeud Papillon (based in Sydney) produce great bow ties (have been buying from them for about 2 years now), and I'm sure their pockets squares are good too. They are pricier than ones you order off eBay, but I can vouch for their quality.
At 30% off their regular prices, it's a pretty good price for good looking and good quality bow ties, and makes it cheaper than ordering it off somewhere like The Men's Shop (even with the $20 discount new members get)
Sale ends on 14/08/12 (meant to be getting in new stock)
What in God's name is a neckerchief? I am that uncultured…
