I think [name_f]Reverie[/name_f] is absolutely gorgeous [name_f][/name_f]- ethereal, whimsical, and memorable without feeling forced. I think the nickname [name_f]Rev[/name_f] works well, I even think a little girl named [name_f]Reverie[/name_f] could easily be called [name_f]Evie[/name_f] or Ri-Ri if you like those as well.
[name_f][/name_f]As far as associations: I’m not aware of any famous person or major brand named [name_f]Reverie[/name_f] [name_m]Tempest[/name_m], so I wouldn’t worry about it being “taken.” [name_m]The[/name_m] words themselves are neutral to positive, though “Tempest” is dramatic and a bit stormy [name_f][/name_f]- but I see that as a poetic flair rather than something unsavory. Of course, it is a bit intense of a name combo as they are both word names, so like others have said, I personally would suggesting picking the one you like more (which appears to be Reverie) and pairing it with a slightly more palatable first or middle name if really wanted to use it for real.
