I will let others with a more varied experience with kilt purchases than I give advice in that arena as I am a wool mid-heavyweight 8 yard tank kind of guy, having used only about 6 different kiltmakers or retailers to fill my closet.

As regards the hose, being 6'5" and 270 pounds plus I have had great luck with every House of Cheviot hose I have purchased as far as length is concerned, with more than adequate turnover on the hose tops. And the variety available is absolutely overwhelming, from the various patterns and multitude of colors to the fancy tops to the tartan tops to the diced and full argylls. I have also had great satisfaction with what are called "piper's" or bobble top hose---not sure of the particular manufacturer but they are available at a lot of vendors, and they also are very long with an additionally long turnover that generally allows for at least two if not three turnovers to get it down to the proper height below the knee over your garters or garter ties. They too come in a multitude of good kilt-complimenting colors, although not as many as the House of Cheviot solid colored selections. Both varieties are good and solidly build and relatively hardwearing and should last many years with good care. Many other varieties from other manufacturers may also be found by searching the internet for "shooting socks" instead of kilt hose, as well as this search bringing up some of the varieties and colors of hose from House of Cheviot not typically included in their line of "kilt hose".

So fear not your height from the hose standpoint.
