What do Mexicans wear in Mexico?

The guy who posted the websites of those mexican fashion shops is really clever. So, there's a reality that may be a little unconfortable for some US girls but let's face it: Latinamerican girls dress so much better! So, you will need some nice jeans, some t-shirts, accesories, a nice purse, shoes. Don't worry about church, just don't wear bikinni or hot pants, there is no church etiquette rules here in Mexico, just common sense, you can wear jeans and a T-shirt and it will be OK
