I used to wear Ballantyne, Pringle, Johnson's of Elgin, NPeal. . .. all of which are either sold, gone stupidly trendy, or out of business. The one enduring rock of Hawick is William Lockie. The company sells directly through its own website or heatherwallace.com
Incredible range of colors, beautiful, tightly woven cashmere, lovely cuts to their sweaters. And their prices, even including shipping and conversion to $USD, are substantially lower than you will pay retail for their products in the USA.
A tip: If you can bite off this much, the company will custom-make you sweaters in their Rolls Royce weight. . .a heavier, beautiful two-ply (their retailers here call it four-ply, but that's bullshit. . .they just use an extra luxurious weight of Todd and Duncan yarn). Here's the thing, though: You must buy at least four. That's the deal. I guess they have to fire up a loom and dedicate it just to your needs.
Thing is, four of their fabulous, luxury weight sweaters, V-neck or crew (or two of each), in an absolutely dazzling array of about 120 colors, costs about what one Brunello Cucinelli two ply goes for. . .about $1600.
I have several. The man at Lockie to talk to is a guy named Allan Gilchrist. I'd hurry, before there's nothing left in Hawick but a cashmere museum.
The Scots are getting their asses handed to them by the trendy names on the continent, and the cheapies in China (which are often one and the same).
