Keira Knightley's bra shows through blouse on New York stroll

KEIRA Knightley must be dotty for this blouse — wearing it despite the fact you can see her BRA through it.

The 27-year-old actress took to the streets in the mesh top with her rocker fiancé James Righton during a break in New York yesterday.

She teamed the black and white polka dot number with high-waisted red shorts, gladiator sandals and a black Chanel bag.

And she swept her dark brown tresses up into a messy bun.

Lovebirds ... the couple are set to wed

Her Klaxons fella dressed down in casual jeans and a white tee, and wrapped a protective arm around his gorgeous missus.

The couple — who got engaged in May — wore matching shades as they strolled around the Big Apple.

Keira is currently in the States to film her new movie Can A Song Save Your Life with fellow Brit James Corden.

The film sees Keira play a struggling musician called Greta, who launches into a romance with a character played by Mark Ruffalo.

Keira is not the only one to have found her Mr Right — James Corden is also set to marry his girlfriend of two years, Julia Carey.

The couple — who have a one-year-old son, Max — will tie the knot later this year.
