So, I'm leaving in the morning to go visit relatives in the midwestern US. I expect it to be pretty hot, so I'm not too worried about keeping warm, but I will probably want some sort of jacket. I've narrowed it down to three choices: faded black/grey jean jacket, cropped black cotton motorcycle jacket, or a grey "sweatshirt" blazer. My travel wardrobe is mainly black and white with a little aqua, plus one cream colored skirt and a pair of blue jeans. All three weigh about the same and would go with all the other items, although the jean jacket might be slightly more versatile.

What would your inclination be? I already have a long cardigan to wear on the plane which can double as a bathrobe/swimsuit cover up.
