Fashion question! maxi dresses? please help?

Hi :) so lately I've been thinking that I really want to try out a maxi dress, and the other day my friend was wearing one and it looked suuuper cute so that encouraged me even more..:) im not sure how to pull it off though.. if anyone has some advice on how to wear a maxi dress? what to wear it with, etc? I'm 5'4 ish (maybe 5'5) and i'm thin with long legs and A cup boobs lol. so if anyone has any advice on how to pull of a maxidress i'd love some help!! thank you xxo
