To feel comfortable in Brazil's sweltering, tropical climate, wear clothing made of light materials and colours that will help keep you cool. Light cottons and similar natural fibers are usually reliable choices.

Keep in mind that the seasons in Brazil are opposite to those in North America; June/July and August is winter and December/January/February is summer.

Appearance is vital in any business culture, however in Brazil the subtle differences are more acceptable; for instance you may wear jeans and a nice shirt and blazer to a meeting and be totally accepted. In Brazil there is a lot more fashion trends in business attire than in the US.

If you are wearing a three-piece suit in winter it is fashionable, but not in summer. Most Brazilian suits, unlike those made in the US, are tailor made and that is what distinguishes your position. One distinguishing factor is if the materials in your suit are local or imported.

Men should wear dark suits in black, charcoal gray, or navy blue. Again depending on the industry, light colours in the summer months are acceptable. Dark is better if you are traveling because it hides any dirt better.

Select ties that are well-made and conservative. There is easy access to imported silk ties, but they are not conservative. They can be very flashy.

Ensure that your shoes are polished and kept in excellent condition. Or if you want to--depending on the industry--you can wear sandals or tennis shoes.

Wardrobe options for women include conservative dresses, suits, pantsuits, skirts, and blouses. While you should dress conservatively, strive for an elegant, rather than 'frumpish', appearance.

Women's nails should be well cared for. Makeup is not a strong feature among Brazilian women,who lean towards the natural look.

On occasions for business entertaining, dark suits for men are the appropriate formal wear.

On occasions for business entertaining, elegant dresses or skirts and blouses are appropriate formal wear for women. That famous 'little black dress' is perfect on all occasions.

The colours of the Brazilian flag are green and yellow. Wearing this colour combination will only make you an object of ridicule. Or, on the other hand, you can say it is an homage, which will be very well accepted.

Even if you're just taking a walk through the streets or shopping, be sure to dress well. Khakis or other pants and an attractive long-sleeved shirt are acceptable for men; women should wear a nice pair of pants or a skirt.
