A bit of a bum note! Maitland Ward shows off chest and derriere in sheer dress... before suffering wardrobe malfunction in second gown

She's no stranger to baring her body in revealing outfits.

But Maitland Ward took things to the next level on Monday night when she showed off more than she bargained for during a fashion show at Mondrian Los Angeles.

The former Boy Meets World star was modelling designer J. Loren's super sexy new collection for Adolfo Sanchez and proudly flaunted her pert rear in a totally sheer dress.

Maitland, who is best known for her role as girl-next-door Rachel McGuire on the 90s sitcom, left nothing to the imagination in the daring gown, having omitted her underwear.

The front was ever so slightly more conservative thanks to strategically placed white and black panels covering her modesty.

Her second outfit at the Creativ PR Fashion Week Collections Presentation was just as daring.

Underwear free: The only thing concealing her modesty were black and white leather triangles

The 37-year-old's breasts were clearly visible in the skin-tight leather mesh dress.

Maitland posed up a storm for the cameras, but seemed totally unaware that her bare bottom was on show due to a small tear at the back of the outfit.  

She cheekily wrote on Twitter alongside a shot of the back of the dress: 'And you thought you had seen it all from me... Sorry, can't show the front. Shooting for master designer J. Loren's fashion show tonight'.

The star has earned a reputation for her daring get-ups since leaving the US show, most recently baring her body in a metallic silver bikini at Long Beach Comic Expo.

Maitland, who married Beverly Hills real estate agent Terry Baxter in 2006, dressed up as comic book character Red Sonja - The She Devil With A Sword.

The fiery red head wore a pair of angel wings on her shoulders, bronze garters and brown leather gloves and boots.
