Concurr with John's assessment of Clansman knitwear. Although I got a great deal on my formal 8yd kilt and the quality is superior, it took months to arrive: ordered it in FEB and my kilt arrived in July. Go figure.
I do highly recommend Tartan Web. Ordered a tailor-made Sherriffmuir formal kilt jacket and it arrived within 4 weeks and fit to a tee. My wife took the measurement as they instructed and their tailor did the rest.
