Looking for a new wardrobe? you might want to consider flying over
On a serious note. You can pick up incredibly cheap flights to Malaysia or Singapore and find great tailors who can produce quality bespoke suits in no time and at ludicrously low prices. Assuming you're interested in buying a couple to bolster up the good old wardrobe, it may be more economical to fly over + you score an awesome week of fun with it - assuming brands are not a priority.
Once you've established a relationship with a legitimate business you can always order it and have it freighted.
