You should wear only the clothes you are comfortable wearing as well as taking off. And all the other clothes that give you anxiety in any way should be either donated or given away in any ways. You could also use them for cleaning surfaces. Sometimes we all need a wardrobe change, buy little and donate others. New energy is good as long as it is positive. Colors are also responsible for how the clothes make us feel even before we wear them. Always save the safest combinations especially the ones you feel most comfortable in for confusing times when you are not sure what to wear. There will always be times when we hardly wear something we bought with such interest and other times we may wear it after much time elapses, may be the right moment. I have recently developed fondness for acotton kotra type trousers that I find easy cool and comfortable in comparison to jeans.
Take care
Well, some things are easier to solve than others. Don't wear gowns or clothes that create the anxious issue for you. However, I'd guess that then something else would surface in its place. But some things can be eliminated and life goes on quite easily and certain kinds of clothes would be on that list as far as I'm concerned. Is it where you are going to that also increases the anxiety? Do you have social anxiety?
I don't really understand, I hope others do but more info might be useful. Do you suffer anxiety about other things? Do you have problems with sexual feelings -- undressing and dressing up can make us feel sexy or sensual, is this a problem for you? I'm asking because I'm trying to figure out if you have a chronic anxiety problem that would indicate therapy would be useful or if this is just one thing in your life that bothers you for some reason.
