I purchased it for one of my personal projects, but I was amazed to learn that it was obtainable. What do you think its value could be?

If used as a brand name, "odd shirts" could be perceived as eccentric and captivating. However, in my opinion, its value is rather insignificant, especially given that it refers to "t-shirts". It could prove to be a challenging sell.

Examine the backlink history of that URL. It appears to have an abundance of unsavory links directing towards subdomains, indicating potential SEO problems.
As a result, starting fresh with a new domain may be an easier option than trying to correct these issues.

This domain name is peculiar. I have no desire to purchase it.
