I even have my own brand of clothing but I don't wear it myself
What kind of clothing does your brand have?
I have a limited edition T-shirt
Creating your own brand can be intimidating to some, so it's great that you have accomplished this goal for yourself. You should see wearing your brand as an opportunity to represent and market your product.
I don't wear it myself because I can't find a size that fits me perfectly.
There is no pressure on you to wear your brand. It's still an amazing accomplishment that you created it, you should be proud.
