Marling & Evans have some shades in their Naturals range: http://www.marlingandevansltd.co.uk/collections/naturals/naturals.html
If you prefer a smaller scale than the LL I think this might be spot on: http://grunwald-true-style.com/product/vintage-houndstooth-tweed-jacketing/
Thanks for the thoughts, guys. I didn't really consider the scale yet. Looking at several houndstooth jackets, you seem to be right.
BTW, can non-tweed houndstooth ever be in good taste?
