if you're of a certain age a mini skirt can look a little ratchet. (says the woman who lives in coochie cutters). i think pairing it with a light blazer brings a little polish.
i found a few worthy pieces to consider...

blazer / skirt / necklace 1 / necklace 2 / tank / bag / shoe
linen stripes and a denim mini. def. my favorite and the most "me".
