Perfect white t shirt

[Pastperfect]

I'm after recommendations for the perfect white t shirt. Preferably something a bit silky, with a bit of stretch that is perfect for wearing under a blazer for work.

I don't mind a bit of embellishment but it absolutely must NOT be see through.

Any ideas?

Came across your message whilst searching for the same so thought I'd add an 'almost but not quite' one from M&S

From your description it sounds like we both want something a little less fitted slightly more luxe (is that even a word ), silky but not necessarily with a sheen iykwim.

Maybe someone else can help.
