Does anyone else get anxiety when they need to buy cloths?

Ever since I had children I have irrational fear of looking put together . I would say 99% of the time my hair is done and I have makeup on but I am in jeans and t-shirt. On the days that I look better I feel weird going out with the kids because I feel like people are staring at me.

When I need to buy clothes, I walk around aimlessly and I don't want to try anything on ( I do though if I don't have the kids with me) and I just get self-conscious. It is so weird.

There is a blue dress from Anthropolgie that was posted on the shopping thread that I loved. I went there and I fell in love with the dress. The picture doesn't do it justice. I wanted it for Easter and for a christening and I just couldn't buy it. What is wrong with me??
