Sheer madness: Kim Kardashian revealed a little too much when her workout leggings turned sheer in the sunlight yesterday
It is undoubtedly her most famous and photographed body part.
But Kim Kardashian showed off a little too much of her derrière after a workout session in LA yesterday.
The reality star wore a pair of stretch leggings for a session at Barry's Bootcamp, but unfortunately for Kim, they turned see-through in the sunlight, exposing just a bit more than she intended.
The 30-year-old held her large Hermes handbag behind her, perhaps in an attempt to conceal the fashion faux pas.
It was Kim's second day in a row at the gym, in the lead up to her wedding on August 20.
While she went make-up free yesterday, the day before she looked more like her glamorous self after applying a bit of lipstick for a trip to the gym with Kris by her side.

With her wedding just three weeks away, Kim is leaving nothing to chance in her last minute bid to slim down for the big day.
The reality TV star has been hitting the gym non-stop and has even enlisted help from not one, but two, personal trainers ahead of her big day.
She has hired Jennifer Lopez's coach Gunnar Peterson and Tracy Anderson, who is famous for her work with Madonna and Gwyneth Paltrow, to whip her into shape.

Kim has said she wants to lose 15lbs before walking down the aisle.
Anderson, who sometimes trains her client twice in one day, tells Life&Style magazine:
'We don’t want to take away Kim’s amazing curves, so we just do specific movements to tighten the skin and to pull the muscles tight against the bone.'
No joke: Kim was glad to leave the gym yesterday after her gruelling workout at Barry's Bootcamp, which is known for its high-intensity fitness classes
Peterson has her doing curls and lunges with him two to three times a week.
On top of that, Kim still plans to continue sessions at Barry’s Bootcamp, which offers high-intensity interval training classes.
Later in the day, Kim was pictured arriving at Mel B's baby shower in Beverly Hills.
Kim was seen leaving for the party alongside her sister Kourtney, with both girls toting perfectly wrapped gifts for the girly celebration.

The brunette beauty slipped her curves into a sheer zebra-print dress cinched at the waist with a thick leather belt for the occasion.
She accessorised the look with a black leather Hermes Kelly bag and a pair of her obligatory towering platforms.
Kim wore her hair slicked back in a tight pony and applied her usual smoky eye and pale lip make-up combination.

In stark contrast to her sister's monochrome look, Kourtney went for colour in patterned chiffon shorts and a peach sleeveless shirt.
The 32-year-old extended her height in beige strappy Christian Louboutin sandals.
Mel B's baby is due later this summer and will be the first child for Mel and her husband Stephen Belafonte.

Announcing the pregnancy earlier this year, Mel said: 'We’re really excited. We wouldn’t have planned and waited for four years to have a baby if we weren’t really excited about it and ready for it. Even though you can never really be truly ready.'
The singer also has two daughters - Phoenix Chi, 12, from her first marriage to backup dancer Jimmy Gulzar, and Angel, four, from her short-lived relationship with Eddie Murphy.
Stephen has a six-year-old daughter Giselle from a previous relationship.
