Hi, Sally, well, to answer your question directly, it’s something that will be different for each person. Keep your eyes open and look around you and see what others are wearing, are doing. And most of all keep doing what you want to be doing.
If I recall, I think there was a time when some people went around mentally telling (or vocally telling their friends) that someone they knew should dress their age. I think for the most part, that time is coming to an end. Oh, people will still do it, but I’m guessing more and more will say in reply, Hey, you do what you want, and let that person do what they want.
As I’ve always felt, as long as you’re not hurting yourself, and hopefully not overtly hurting others, you should be free to do whatever you want for as long as you want. (and by ‘overtly…” I mean for those you don’t know or don’t care about, just don’t physically hurt them, for those you do, try to work out understandings if you can so you both can live with both your choices.)
What I’ve never understood is one of a couple saying in effect, hey, ‘I’m going to do whatever I please…but you have to toe the line.’ That is not a good relationship.
