What do I do if I don't have any clothes?

No, I don't just mean "I don't really like my clothes" or "my clothes aren't universal enough" or whatever. I literally have almost no clothes: maybe like 5 T-Shirts in total, 2 pairs of jeans, some socks and underwear. The issue is not just with me disliking my clothes - the issue is that half of the time I'll wake up and find out that I have zero clean clothes to wear.

Luckily, this is not a financial issue, and I can afford to get clothes. However, I have absolutely no idea where to start. Most of the information online exists with the assumption that you already have some sort of a wardrobe that you want to expand. I tried just going to a mall and going into every clothing store, but I end up not liking most of the stuff there and only buying like a single shirt. I know that that's how most people buy clothes, but again, those people usually already have enough clothing, so buying a single shirt is fine for them.

At this point, even just thinking about any clothing-related activities immediately trigger severe anxiety and dread in me. I feel very lost and don't know what to do.

Can anyone please suggest what to do in a situation like this?
