I just got my first Aqua City and because it is not broken in I am having trouble wearing it over the shoulder (or maybe its because my arms are too big ). Anyhow, I see pictures of girls wearing it on their forearms and let the bag hang that way. It looks lovely on them but when I do it the straps leave my arms red and flushed. Am I carrying too much on my bag? Or does this happen to evreyone? DO you change positions every now and then? What do you do?
