So you can imagine my surprise when I tripped upon a Marks & Spencer ad that looked like this:

Apparently, the model, Natalie Suliman, was as surprised as I was:
"I nearly crashed my car when I saw the advert for the first time," the Sun quoted her as saying.
"I was happily driving to a shopping mall with my music blasting when I suddenly saw a 20ft picture of my chest on the horizon.
"It was shocking to see my boobs looking so huge, but I guess that's not something I can complain about! I'm just happy the advert has been such a success," she added.
What's funny about this campaign is that Marks & Spencer is no Victoria's Secret or Frederick's of Hollywood. I always thought they were such a conservative brand. Just this week, they were named "Britain's most reputable firm", and their environmental sustainability plan has been positively reviewed by Ethical Consumer.
But when profits sag, I guess there's nothing like boobies to boost undie sales.
Grandma would've been shocked.

This is old news now, but I just found out that there was a hilarious next chapter to this story. It turns out that consumers of Ms. Suliman's... umm... stature were offended that M&S actually charges more for larger sized bras.
Here's the modified ad they ran as an apology:

Gotta love the Brits.
