Britney Spears pose in a flirty dress with extreme side cutouts
Britney Spears may have kept fans guessing about her Halloween costume, but she chose to surprise them with something even better: a DIY fashion display.

On Tuesday, Oct. 31, the pop artist released numerous videos of herself posing in front of a full-length mirror at home wearing several sorts of dresses, ranging from fun and flirty ensembles to more expensive ones.
The first modelling video was set to Janet Jackson’s “You Want This” and featured the 41-year-old donning a silver little dress with cutouts, a blinged-out crystal bodice, and a trendy neck scarf. “Hi!!!” she simply captioned it.

Spears then posted a second video of herself cradling her cute new puppy while dressed in an extremely flirtatious sheer black dress with side cutouts that extended from her breast to the hem of the ensemble and silver chains to keep the skirt from sliding too much.
The video was made to J Balvin and Willy William’s “Mi Gente.” It included the same caption as the first-“Hi!!!”-but was shot from a different angle to show off the nicely decorated and lit-up Christmas tree she’d already erected.

Last but not least, Spears wrapped up her modelling stint with another video shot in front of her holiday decorations. This time, there was no caption, and she chose Madonna’s “Addicted.”
She wore an asymmetrical crimson floor-length gown with a thigh-high slit and a circular cutout that went around the left side of her body.

While Spears did not appear to dress up for the frightening event, several of her Hollywood colleagues, like her BFF Paris Hilton and Jessica Alba, used her as inspiration for their own costumes.
