annep I think I've got the same Robell trousers as you with the deep cuff. Also their ankle grazers with a small seam vent. I have them in black, navy, silver grey, sage green and beige.... ooops... sand. They are quite expensive but I know which two styles I like and keep an eye out for them on eBay. They go like hot cakes.
Sand/honey/beige is one of the most flattering colours near my face. I often drape a particular 'beige' scarf around my shoulders over another colour. But as previous poster mentioned, there's beige, and then there is beige.
I really believe that for a classy look it's hard to beat 'sand' with black or grey or navy, with a touch of white.
It's all about the cut, the quality, the fabric.
