I'm not over keen on these grey tartans but as long as you like the look that's really what matters

You have not said where you plan to buy this kilt or whether it is wool or not. If it is wool then I say go for it, but if it is not then have a look at Hector Russell and consider one of their made to measure kilts at the same £199 price. They should do the Marton Mills grey equivalent of this tartan and it would be 100% wool. It will be machine stitched but excellent quality

I'm also not convinced about the "brown" stripe. I think it's probably grey
