I am perplexed by these jeans.

1) I purchased them thinking they would be a fun way to wear jeans and a colorful t-shirt or simple blouse, but I can't figure out what to wear with them except navy blue and maybe white (although there isn't any white in the jeans, only the lightest of blues). I can't figure out what shoes. I thought they would be as versatile as regular jeans and I'm drawing a blank.

2) is it going to be weird to have 50-year old me in these?

3) are these an older trend? I bought them at the Rack so I don't know if that means they are a trend that has been around for a long time or not?
