I've seen a few of the usual 'where to get clothes' threads popping up here and on the expat oriented FB pages...
I do all my clothes shopping at www.marksandspencers.com these days and the service is brilliant...I just had 3 new shirts delivered that I ordered on Friday...DHL delivery to my office, 15 quid.
Worth a look...especially if you need *ahem* elastic waists in the Chinos these days...
