Stassie slipped into a sequined gold bra-lette that emphasized her cleavage and allowed her to flaunt her sculpted midsection.

She teamed the barely-there top with a slightly sheer skirt that was cut dangerously high, displaying her legs to full advantage when she squatted for one snap.

Accentuating her features with makeup she heightened the leggy effect of her outfit with heels that featured straps going all the way up to the knee.

Stassie was posing up for Instagram in front of an elegantly backlit set of shelves that were lined with several bottles of wine.

The leggy sensation, who tagged London jeweler Anabela Chan in the snap presumably as a photo credit, wrote in the caption: ’24 tomorrow.’

She was treated to some gushing Instagram comments including from Kylie’s older half-sister Khloe Kardashian who wrote: ‘So so beautiful.’

The previous evening she had posted footage of herself in the same outfit to her Insta Stories and declared: ‘bday festivities start tonight.’
