Oh, yikes, having to worry about the scale of prints is new. I guess I am "big boned" in that my wrists measure larger than most other people I know, even those who are taller and heavier than I am. I have a friend who is considerably larger than I am in all ways, but her wrists are TINY, and we can see the difference even just holding our arms out next to each other. Like Sal mentioned, I am also broad shouldered and have a strong jawline.
But, I am bordering on petite in stature (right around 5'4"), and wear about a size 4. So... being big boned, should I be able to wear large prints? Or given my stature should I stick to small? Ironically, I just purchsed two dresses, one with a small print and the other with giant flowers - and I liked both! But I think I only considered the silhouette and whether they were flattering to my midsection (the area about which I am most self-conscious). Perhaps I need to take pictures and put them up for opinions.
As for jewelry, I don't really care, because I like statement jewelry! I either wear lots of layered, real jewelry, or big, noticeable pieces in paste. Whenever I'm wear a solid colored top, I will wear jewelry that can be seen.
