Sand Dollar Shoes

So this is my fifth year at camp this year and I'm 14. We have a dance with the boys and I wanted to know if you thought it was an appropriate costume. FYI, the theme is Hawaiian, but older girls are not usually dress. In fact, nobody has really done!
Here is the place:
Black short sleeves, scoop neck shirt equipped Nordstroms
Light wash denim skirt is a little frayed at the bottom from Forever 21

Shoes:
flip flops Clark White flowers that have leather (sports shoes, not patented leather)

Jewelry:
Silver necklace with a dollar of silver sand which is about an inch and a half in diameter

Should I wear earrings?
Do you guys have any suggestions outfit? Should I wear this all? And what do I do to my hair? My hair does not derive from the beach disorder, look, I thought straight ...
Help please!

I think this outfit would be perfect if you think it looks good, then you should wear it. My hair does not work well with something as latelyy I pull back into a low ponytail on the side a bit and I think that goes with anything. I wear all the clothes if yes. And the earrings, you should find that pair that you think goes with the costume. I would go with either a set dollar little sand or a pair of little green, orange, or maybe pink. those that the small dot. I wear them everywhere I go, if I do not know what game to wear.

ithink its sounds good u should wear earrings
