The clothes

In Brazil, in the summer we wear lights clothes because it's very hot. The mens wears shorts, t-shirts, sandals and sometimes the mens walking by the streets doesn't don't wear t-shirts. The womens wears shorts or skirt, t-shirt and sandals too. We use sunglasses and sunscreen. The winter don't  doesn't get cold in somes regions, for example, in the Nordest (Do you mean Northeast?). However in the South it's very cold and the people use pants, sweaters, boots, socks, scarf es and sometimes hats.
The Brazil is the country of Havaianas (Brazilian sandals known in the world).
