To get a Feebas to evolve into a Milotic, go to Pallet Town (you can gain access here if you beat the elite four) then go to Blue's house where you'll find Daisy Oak. Then, let her massage Feebas but here's the hard-to-wait thing,... Let her massage Feebas 7 or 8 times everyday. Then, when you transfer it to Pokemon D/P/PL, you can see that the beauty stat is to the max level. Now, level it up and watch it evolve into a beautiful Milotic!

In Pokemon Black And White, Feebas will evolve into Milotic by happiness, and, as i recall, berries, this process is easier if it were 'Poke Transfered' from Platinum, Diamond, Pearl, Soul Silver or Heartgold, as you can feed a Feebas Poffins (Beaty) until it won't take anymore. Than you level it up once and it will evolve into Milotic.
Anyway, to evolve Feebas into Milotic, your Feebas has to have its max beauty, then after that level it up by 1. And then Feebas will evolve into Milotic.
Feebas does not evolve by level in Pokemon HeartGold. Feebas evolves when it levels up while it has a maximized beauty condition.
If you get it 8 haircuts/massages and then level it up, it should evolve. Galceon, Leafeon, Megezone, and Probepass must be traded for.
