The first piece of tan I got this year was on a particularly sunny day around March/April I think it was.
I was still wearing a jacket and full finger gloves, but the jacket rolled up a bit leaving a one inch gap, I thought nothing of it. When I got home in the shower, I was horrified to see this band around my right wrist! It's still the darkest part of my tan now about an inch thick.
Now my tan is sort of 3/4 of each finger, a circular part on the back of hand from gap in glove, then just above wrist up to upper arm. My knees themselves are much darker tanned than my lower legs, which are also tanned. Every other part of my body is very white as is my complexion!
I am not sure whether a patch tan is better or worse than my usual no tan (I am actually a computer programmer, and the image in the post above held true for me in previous years!)
Here is part of my hand!
