No nonsense coffee, you get what you order

But then how will i look cool

No, no, wrong. Flat white, latte, and cappuccinos all use stretched milk, they're all "frothy" and they're all "milky". Flat whites have less air introduced into the milk, lattes have a moderate amount of air, and cappuccinos have the most. Flat whites tend to be heavier - both physically and in the mouth - while lattes and cappuccinos are lighter.
