Welcome to the fourth installment of Stage-to-Street, BritneySpears.com's fashion series which takes all of Britney's awesome concert costumes and turns them into outfits for every occasion. This week, we are translating Britney's 'Womanizer' stage look into a sleek, business ensemble perfect for the office.

1) Sequin Tie Button Up Shirt / KBT Direct ($22.99) - This shirt and tie combo are perfect for getting the 'Womanizer' look. The tie even has sequins all over it just like Britney's.

2) Thin Sequined Black Scarf / Journeys ($10) - If you already have a dress shirt or ties aren't really your style, try using a thin sequined scarf in place of a tie. It adds a modern, feminine touch to this look.

3) Sterling Silver Script Initial Pendants / Eve's Addiction ($29) - Brit put her stamp on this outfit with a "B" initial cap. Bring some self pride to your own outfit with a classic initial pendant. It gives a nice, personal touch and never goes out of style.

4) "Mogul" Black Patent Lace Up Ankle Boot / Michael Kors ($197.50) - We've paired these ankle boots with several stage-to-street looks, as this style of boot has proved itself quite versatile in many of Britney's 'Circus Tour' routines. A BritneySpears.com insider even spotted several pairs of boots just like these backstage during rehearsal.

5) High-Waist Lace-Up Corset Pencil Skirt / ChicStar ($21.95) - This skirt pays homage to the cop-corset Britney wears on-stage during her 'Womanizer' routine and the sexy secretary outfit she wears in the 'Womanizer' music video. With this skirt you get the best of both worlds at an affordable price.

Welcome to the third installment of Stage-to-Street, BritneySpears.com's fashion series which takes all of Britney's awesome concert costumes and turns them into outfits for every occasion. This week, we are translating Britney's 'Piece of Me' stage look into a glitzy, textured ensemble perfect for a night of dancing at the club.

1) Almost Famous Sequin Vest / Sears ($9.99) - This tanktop with a built-in, sequin vest has an uncanny resemblance to Brit's 'Piece of Me' top. Get it while it's hot though, as this little number is on sale.

2) "Sermide" Belt / Aldo ($30) - This double-buckle belt has a great corset-inspired vibe. Just belt it over the shirt around your upper waist to complete this fun and frisky look.

3) Lamé Black Shiny Leggings / American Apparel ($42) - These are the same leggings that were paired with Britney's Stage-to-Street: 'Circus' look. They are very versatile for mirroring several of Britney's stage outfits. You can cut these liquid-like leggings to your preferred length (remember to SAVE the remaining leg scraps for the Stage-to Street: 'Get Naked' look - coming soon).

4) "Mogul" Black Patent Lace Up Ankle Boot / Michael Kors ($197.50) - These ankle boots were also used in Britney's Stage-to-Street: 'Circus' look. A BritneySpears.com insider spotted several pairs of boots just like these backstage during rehearsal, so this style is definately a key piece in mirroring Britney's stage outfits on "The Circus Tour."
