Barry M Vivid Purple available here
Barry M Vivid Purple no 161 is a exactly that, a vivid purple. With a super shiny metallic finish, it only needs two coats for a thick opaque finish and lasts around 4 days before looking worn. It doesn't even need a top coat and the polish itself is thick but not gloopy.
I'm not really a purple polish fan these days but I do think this is a lovely colour and a bargain at £2.99.
