Wiggin' Out for Britney

What do you do when your wigs look like hell? Send your cousin out for some new ones!

Britney Spears' kissin' cousin Allie was snapped at The Wig Company in Studio City, getting a grip on Brit's next look ... which looks like it's going to be Marcia Brady at the prom ... and/or Pam Dawber as Mindy.

Allie is Britney's assistant and sometimes driver ... and now, apparently, head manager.
