I bought one size bigger in JonesWares than I wear in Smartwool bottoms, and they're just right. I'm a little curvier below the waist (can't wear Ibex bottoms at all) and both SW and JW fit me nicely.
I wouldn't be concerned about seeing through the JW tights at all - they're very heavyweight. The SW long bottoms might be see through, but honestly for running I wear wool underwear underneath them so I can wear them multiple times without washing, and for day wear they'd be better under a longer top or tunic anyhow just appearance-wise.
