Some signs:
1: He is lingering too long at the item – a non-T guy would look at it, know his wife’s size and buy it.
2: Lurking – looking edgily at clothes and walking away when a woman approaches -a non-T guy would ask another shopper for advice.
I used to do this when I thought I was a TV and struck up some great convos even down to admitting I wore women’s clothes.
3: Eyes and shoulders stooped – a total giveaway to any person dressed or not.
It is the “I am not authorized to be here” look. A non-T-guy or a confident T-girl has his/her shoulders back and head up.
4: Spending too long on the Sale aisle with short skirts in their hands and no trolley.
Tip – take a trolley, load it with a newspaper. a woman’s magazine, and cereal.
