Dress how you like in TJ, me I dress casually as really you don't have to dress up to impress the putas.,because they are more worried how they are going to impress you; as there is lots of competition for your American dollar from younger prettier girls.
If your married you might want to keep your 'wedding ring' on. It's turns on many of the chicas that they are doing another women's husband, and it's a great conversation, when she'll ask, 'if you are married what are you doing HERE?' However a few putas will think you're scum for cheating on your wife, but I think the majority will have more respect for you, and they feel safer with a married man, knowing if he 'CHEATS' he'll probably wear a condom, and that he is not a total LOSER, because at least he has a women at HOME.
