The wavy "beachy" hairstyle you see in these photos were a result of Bumble & Bumble's Surf Spray and a little bit of hair twisting and ruffling. It's supposed to give you the "beachy waves" that occur after you go for a swim. The product sort of works on me, but it doesn't give me the wavy results I originally wanted. Sadly, I returned it.
On another note, I love the ombré effect on this printed t-shirt. I don't own anything like it and am happy to have it in my closet. For those interested, I'm wearing size US4.
