Need help picking out bathroom mirror?

remodeling bathroom tub,surround,commode white...walls a teal blue,fixtures brushed nickel...chose to paint the vanity since it is solid wood and has lots of storage rather than replace....The light fixture above the sink is 5 globes contemp style in a brushed nickel. faucet contemp with brushed nickel and sink white...Should I match the mirror with the vanity color or should I go with something like a frame less mirror.I don't want something heavy.but should the mirror match the vanity color or the brushed nickel lights thanks
