Rihanna Uses Her Side Boob To Promote Her River Island Collection!

Why bother with an ad campaign when you have 7 million Instagram followers counting the minutes until your next upload?
Rihanna turned to guerrilla marketing tactics to promote her River Island collection, posting more pics of that seksi denim overall-style crop top on her account.
It looks SO much better without any clothing underneath, doesn’t it?
We can’t imagine anything motivating people to buy this collection more than RiRi’s side boob! And abs!
The singer styled her all-denim look with gold Chanel platform sneakers and a backwards cap.
We know this is going to come as a surprise, but this overall top is really growing on us.
What about U???
