I think simple jewelry is acceptable. Not recommended necessarily, but allowable if moderate and discreet.
However, large, dangling earrings, or noisy "charm" bracelets, or layered necklaces (and particularly those bright, chunky necklaces that are derived from tropical or African locales ... I personally find "too much" for any circuмstance .. and definitely not at church!)
Appropriate clothing would consist of non-tight fitting skirt or dress, falling below the knee, most of the chest should be covered, just under collar bone acceptable, nothing sheer, and avoid bright colors or "busy" patterns.
Frankly, for me, red really bothers me. It's just too intense, too "look at me!" I prefer subdued colors, pastels, pale types, either no pattern or a very subtle pattern. I don't like to wear more than 2 inch heels .. and even at that, I rarely do.
As was discussed in a previous thread: the wearing of high heels or high heeled boots is inappropriate. I had been looking at boots for some years and was returning again and again to low heeled riding boots. I realized then that the pointed toe, high heeled boots were immodest, even "sexy" in themselves, regardless of whether a woman wore a longer skirt and was covered everywhere else.
I am so tired of seeing black everywhere! At Mass a couple of weeks ago, the children who were receiving First Communion were all dressed in white. Their mothers? Most in black. Black pants, scoop necked tops.
I've been seeing more and more black on little girls too. Last week, a darling little girl was allowed to come to Mass wearing a fuschia ("hot pink) tutu and a BLACK LEATHER JACKET! :shocked:
Needless to say it was both ugly and inappropriate.
Maybe all the black is because we're in mourning for the death of our culture? :sad:
