Summer I like medium (stop right @ or above the knee) and long dresses and or skirts! All the rest of the year I wear strictly medium length attire. :) But it must me form fitting or slightly loose. Never short stuff.
I sometimes wear dresses in summer. I like short and maxidresses. I do make sure that the short dresses are not too short and not too tight. Maxidresses are just super cute and comfortable, but besides that, I'd rather wear some pants.
Girls like wearing short dresses when they want you to fuck them. Girls like wearing medium dresses when want you to respect them. Girls like wearing long dresses when they want you to leave them alone.
