Cheers Milo - though im not sure if maybe they're all a bit dressy for what im after, i was thinking along the lines of GANT / Ralph Lauren / Paul Smith, something which can be dressed down when not paired with a suit - but being a scrubby old Electrician who never wears suits im not sure how their shirts dress 'up' if you know what i mean. Do the places above purely tailor for formal wear?
J Crew are worth a look

the sale is still on and they will have more stock in the shop than is available on line.
Your other option would be one of the department stores.
