I got mine from AmirEqui which is linked above. I have ordered quite a few pairs of breeches from them so felt very comfortable ordering the Shadbelly from them. There is no VAT on orders shipped out of the UK and their website will figure that in when doing the order. I did double and triple check that I was ordering the correct US size and not the UK size. If you do order from them they ship it Postal but someone has to sign for it otherwise it will have to be picked up at the post office.
Mine came in within a few weeks of ordering it and it is just like a Pikeur that I would have gotten in the states but cheaper!
