All aboard the Soul Train! Big-haired birthday girl Beyonce teases her VERY low-cut fancy dress costume as she and Jay Z lead showbiz pals at her 35th

She's usually the star of the show, but Beyonce went above and beyond on Monday night for her birthday party. 

The 35-year-old rang in her big night with a Soul Train themed bash, which attracted some big names - as well as some incredible fancy dress costumes.

Busty Beyonce teased only a glimpse of her retro and racy ensemble, draped in a long coat, as she arrived on the arm of her husband Jay Z, 45, for the New York City party.

The musician wore her hair big, like a throwback to her role in Austin Powers' 1975-themed Goldmember film.

She tipped large, round glasses on the end of her nose, keeping her head down as she let her legs do the talking in fighnet tights. 

Beyonce seemed keen to keep the rest of her ensemble under wraps and closed her long coat, which was robed over her shoulders.

Take your style to new heights in Beyonce's platform sandals

Beyonce seriously went for gold at her 35th birthday party this week after choosing a Soul Train theme to mark the occasion.

The star chose a very low cut top in a metallic hue and a coat too, finishing things off with golden heeled sandals.

The heels by Giuseppe Zanotti gave the look serious wow-factor and we couldn't help but lust over the super shiny pair.

If you're a magpie like we all are, you're going to love them, so why not click through to Nordstrom (right) where you can snap them up?

But if you're out of luck size-wise, then check out the alternatives we've lined up below. Public Desire offers up a bargain buy, but we adore the Terry de Havilland pair at ASOS. If silver is more your metallic hue though, head straight for the Topshop or River Island options. You'll be high stepping like Beyonce all night long!
