Miss the memo? Red-carpet ready Kylie shows up her scruffy beau

She's one of the most glamorous and impeccably styled young celebrities out there: yup, Kylie Jenner rarely looks anything other than totally immaculate.

And on a night out with her long-term beau, Tyga, last night in West Hollywood, the 18-year-old reality TV star certainly donned head-turning attire.

Dining at The Nice Guy restaurant, Kylie wore a black long sleeved Steven Khalil jumpsuit complete with plunging neckline (wardrobe malfunction alert!).

Carrying an Hermes clutch and walking tall in black stilettoes, Ms Jenner completed her red-carpet worthy look with the addition of a striking full-length leather fringed belt.

Tyga, on the other hand, was entirely dressed down: he opted for ripped scruffy jeans, a black jumper and – gasp! – even a beige baseball cap.

Controversially, the 25-year-old rapper also wore a pair of black man Uggs.

His wardrobe can't be all bad, however: earlier in the week, Kylie was seen at the Glamour Woman Of The Year awards wearing one of Tyga's oversized denim jackets.
