I started with OPI DS Coronation, a scattered silver holo. Very sheer! I wasn't worried about VNL, though, because of the glitter. For a DS, I was expecting a little more impact, though.
I really liked these two together! BL Henley Regatta would have likely been opaque at two, maybe three coats at most - it was definitely thicker than I thought it would be.
If you're a Butter London fan, stay tuned - I went a little crazy with their last Friends and Family sale, and I have lots of BLs to show you in the coming days!
