Or is this not even the right question? I've got two dresses that have straps instead of sleeves; not thin and stringy, more like pinafore style width. I love the dresses but I feel naked (I'm new to dresses!) and I want to wear a top underneath. To my mind that can be quite a "cute" look and I don't know how to tell if it flatters me or not (and I can bear to post a pic, sorry!). So what am i looking for to help me judge this? Is there a certain style or shape this looks best on?
