With her Chanel shades, it’s clear Lindsay Lohan can afford a bra too whether designer or WalMart.

Yet it appeared to have slipped the Mean Girls actress’ mind when she was getting ready yesterday.

The actress was seen shopping at a vintage store in Venice without any support for her rather ample 36D bust, causing them to sag a little as she showed off sideboob during a cigarette break.

Arguably, the white halterneck wouldn’t have had quite the same summer chill-out look with a chunky bra strap ruining the backless effect, but an underwire bikini top wouldn’t have gone amiss.

Unfortunately for LiLo, the downside of being blessed with a generous bosom often means they have a little difficulty defying gravity and a tendency to go walkies south.

But unlike the plastic fantastic stars of Tinseltown, it is no doubt refreshing to see someone proud of their natural curves.

Lindsay teamed the look with white pumps, a pair of denim shorts and a chunky silver bracelet.

And it seems the arduous task of shopping proved a tad strenuous on the New Yorker, as Lohan soon needed a cigarette break halfway through scouring the rails of the Los Angeles store.

During an interview with Cosmopolitan, Lindsay previously confessed: ‘I don’t really like talking about it, but last I checked it was 36D.’

She also told Cosmo Girl in 2005: ‘I developed late in school. When I was 16, I still had baby fat. I didn’t get my chest until I was 17, so that made me insecure. I used to feel like I had to stuff my bra.’

However, last December, Lindsay was far from shy about her figure as she posed for Playboy.

At the time she revealed: ‘Sex and sexuality are a part of nature, and I go along with nature. I think Marilyn Monroe said that, and I agree with her.

‘Knowing your body and being in touch with your body is important because it gives you confidence, and in life, women need confidence.

‘It’s a very male-dominated world, so knowing yourself and being comfortable with your body is an important thing for me as a woman.’

The redhead, shopping yesterday with brother Cody, has just wrapped filming on The Canyons, starring alongside porn star James Deen in the Bret Easton Ellis scripted film.

And following a career nosedive that threatened to send her spiralling into oblivion, LiLo is back on track with roles in Machete Kills, Scary Movie 5 and the recently completed Liz & Dick.
