If you have, you know your boobs don't really like to stay put with all the movement and twists and upsides downs and etc.
Ultimo has come up with a sexy bra to solve the problem, as well as the best advertising campaign ever.
Namely, a video of a bunch of girls in lingerie riding several rollercoasters at Allton Towers Resort.
This video may be the best thing I've ever seen.
Also, on that note, I can hold up to six phones in my bra on a rollercoaster and not lose any of them.
I have it.
