ball...

Chey
So I have my ball (prom) in about 6 weeks and the theme is Under The Sea. 
My boyfriend is going to get a navy blue suit to match my dress (will post) but I just want something little that he can put on his suit and I can put on my dress that kinda goes with the theme. Yanno, like how guys have something in there pocket that's visible. But I want it for the both of us. What's some ideas? I hope this make sense. It does in my head but I can't seem to get it out with words 😂
