This is the OP.
Thank you for all the responses. It sounds like it is acceptable, but not ideal.
I only have a tiny handful of good dresses/skirts, and all are rather heavy for summer. The denim skirt would be much cooler. Like one poster mentioned, I really appreciate how it's made of a sufficient weight of fabric and not at all clingy. Almost all the skirts and dresses I can find of acceptable length that are light enough for summer are of such clingy, lightweight fabric that I would never wear them even at home. I can't afford to buy clothing outside of the thrift shops or else really on sale.
I wish I could sew well. My mom never wanted to teach me how to sew and I've never could ask anybody else. I'm not in a position to take a class. Unfortunately too, fabric is quite expensive and at least at the beginning, I could see myself ruining some. :sad:
When I can find an opportunity to do so, I'll learn how. I agree that is the best. I wish our churches and chapels would gather some people together to teach us how to sew modest clothing.
I think I'll try to find a nice dressy blouse around here if I am going to wear the skirt. The skirt is darker denim, and not faded at all, so it's a little dressier than some I've seen. I want to be respectful of the One I'm visiting, but if I have to down-dress a little bit in favor of modesty first, and wait until something better comes along, then that's what I have to do. I could wear a slightly dressier cordorouy dress I have, but I also don't want to pass out if it's really warm. I guess I'll see what the weather's like.
Thanks again!
