truth be told, you do get whatcha pay for. As you found one numerated in GBP, I will assume you have to pay VAT and dont have much of a shipping issue. The lenth as stated by others is a concern.

My tuppence, the construction of one is not difficult, the satisfaction immense (but habit-forming) and the fit is custom. A PV first kilt is great, you will hunger for more (my first was cotton, sewn myself, about a year ago. I am now working on kilt number 3 and bought another one as well; have cloth for a fifth and am lusting after some more material. So be thee warned)
