Britney Spears' Geekiest Fashion Moments (PHOTOS)


We can't believe that Britney Spears is 32 years old!

The pop queen, who celebrates her birthday on Monday, has gone through a lot of fashion highs and lows since she hit the big time as a precocious teenager who made schoolgirl clothes chic in the music video for "Baby One More Time" in 1998. (Yes, that was a fashion hit.)

Since then, Spears has dazzled us (see the sequin nude two-piece she sported at the 2000 MTV Video Music Awards) and made us scratch our heads (see the matching Canadian Tuxedo she sported with then-boyfriend Justin Timberlake), but even if we didn't understand her outfit, Brit's ensembles always got us talking.

But the mom-of-two, who is getting ready for her Las Vegas residency, didn't always wear high-octane clothing.

In fact, when she was still just a girl (not yet a woman), the blond beauty actually looked, well, geeky!

From oval-shaped glasses to massive scrunchies, the "Britney Jean" singer's closet used to contain a whole bunch of outdated and hilarious fashions.

So, in honour of Britney Spears' birthday, let's take a look back at some of her not-so-fashionable outfits:
