I could buy Tico clothing, slab on coats of Man Tan, and I still wouldn't ever be taken for a Tico. Very few Ticos are ever as big, and fat, as I am.
Everything in life is viewed as different, not only due to age, but by the individual, and their psyche. I would look like a fool dressing in clothes of someone 1/3 my age. Come to think of it, I probably look like a fool anyway, but....
I grew up in Compton. My friends were of varied ethnicities. On of my black friends told me after the first Watt's riots; "Sh*t dude, I should have taken some of the "white boy" clothes for you. All the white peoples clothes were left on the racks." I still chuckle when I think about the looters looking at the "white boy" clothes, and wouldn't even take them for free.
What I find even more amusing, at 60 (my age) my dad's idea of a good time was going out and square dancing!!!!!
Dress however damn well it makes you feel good. Phuck everyone else as long as you're clean.
