How To Get A Guy's Attention?

Ciara
So there's this really cute guy that helps out in my self defence class/group at college (UK) but i find it really hard to be myself around him. Plus, it's all girls in the class so I feel like I just kinda blend in 😕 Does anyone have any advice on how to 1) Act like myself and 2) Maybe grab his attention? 
Thank you so much lovelies ❤
