Yeah, overthinking....I have been accused of that my whole life. So it's probably true.
Since I retired I spens a LOT of time surfing the internet, probably 8 hours a day or more. Did I hear someone say ADDITCTION? I am also frugil (cheap), most of my life out of necessity (poor). So I am also a bargin hunter. Put it all together........I received the Sun GI when I signed up for Karate, no problem. Then I looked around and noticed what others were wearing, brands. But being frugil I started looking on line for slightly used GI's being sold for less than new prices. There are some real bargins out there, if you can find them. The GI top in question cost me $15 size 4. But when it came it was to small, must have shrunk when washed incorrectly. But it was only $15. I gave it to another student who was excited to get it.
I found a "Karate uniform, heavyweight cotton $40" on facebook market place! Turned out to be a Toyko Shureido. But seller doesent ship, pick up only. They are in Sunnyvale, Ca., and I am in Michigan. so That didn't work out but the search was fun. Currently my time is free. what else can I do. I post questions on various forms. Thanks
