I assumed rick Owens suggestion was a joke. Experimenting is great but when you dont have access in person to brands it can be expensive and frustrating. Maybe you have the patience for it, but I really don't.
With that said, try a WvG tee stitches. lightweight with good drape, long (you may even need to hem), normal neckline. I can't guarantee how it will look on your body, but they're pretty nice. Only $25 with loyalty discount.
+1 on the WvG tees. For the (loyalty) price they're pretty much unbeatable right now. If you want something a bit thicker, John Elliott & Co tees are solid. (Does anyone else find the JE&Co SF thread a little weird?)
