Wearing more black clothes will make you slim, and vertical striped clothes will also make your eyesight slim. ? You'd better not wear bright clothes if you are obese. Wearing trousers or long sleeves is a good choice. Avoid fabrics with large patterns, stripes and checks, and choose simple, plain clothes with slightly narrow shoulders. Choose clothes with an open collar style. Don't close your collar or T-shirt. Appropriate clothes can make people with good figure look taller and slimmer, while people with poor figure look much taller.
