Gwyneth Paltrow in entirely sheer side panels dress and no underwear at Iron Man 3 premiere

Gwyneth Paltrow arrived on the red carpet at the El Capitan Theatre in Los Angeles, California, for the Marvel’s Iron Man 3 premiere, in a gown which looked demure from a distance.

Gwyneth Paltrow’s Antonio Berardi dress featured mesh panels down the sides, showing off her hips and décolletage area.

The material would have made it almost impossible for her to wear underwear beneath the number.

While she could have quite possibly been wearing a strapless bra, briefs would have been too tricky.

The look of her item of clothing – which created the optical illusion of a curvy white silhouette down the middle – also drew attention to her tiny waist.

With a dark green peplum section that matched her kimono style arm cuffs, 40-year-old Gwyneth Paltrow- who plays Pepper Potts – looked in great shape.

She is known for taking up often strict healthy eating plans – such as eating only macrobiotic meals at one point – in an effort to stay trim.

Gwyneth Paltrow allowed her skin to glow in natural make-up and wore her blonde locks straight and to one side over her shoulder.

She added a fun twist to her appearance with purple nail polish and paired a large drop earring with a contrasting small stud that evening.
