My Viccel order arrived today, after around 8 business days. I ordered the size 10-11.5's in the Winter Weight, and the OTC models were approximately 26 inches long, with the mid calf measuring 18. I think they're an absolute bargain for the price, they look and feel great.
I was just thinking about this the other day. Light gray would work too, and I thought an olive pant on the paler side would be interesting. As long as you stay on the pale side for shirts, I don't really think you can go wrong.
