Taylor Swift wore a cheap designer black corset top and an upside-down ‘T’ necklace while out in Sydney on Tuesday night.

The megastar exited the Surry Hills restaurant Pellegrino 2000 wearing the Chicca black shirt from cult brand House of CB.

She wore the fashionable shirt with a brown belted pleated skirt and a T-bar necklace by Tilly Sveaas.

Taylor Swift fashion fans best act quickly if they want to get their hands on the items, since anything the superstar wears sells out in a matter of hours.

Despite her $1 billion net worth, Taylor wore the Chicca black shirt, which costs $169.

The top contains threaded ties that meet in the middle of the bust, as well as front-clasping hook and eye fasteners, allowing you to make it as loose or fitted as you choose.

It is available in sizes XS to L+, with A-C cup or D-E cup options.

Aside from black, the top is available in white with two flower colour options: ditsy red roses or lovely blue blooms.

Customers in Australia can get Chicca online from House of Cb with free shipping or in-store at Myer or David Jones for $176.

Taylor wore the Gold T-Bar Curb Link Necklace by Tilly Sveaas, a British company, around her neck.

The item costs $590 with a 40cm chain and $695 with a 50cm chain; some admirers believe the ‘T’ style is a subtle nod to her Super Bowl-winning boyfriend Travis Kelce.

Tilly Sveaas’ T-bar collection includes a variety of identical necklaces with different chain lengths and widths.
