1: You can choose to install a slender oval or rectangular mirror with a width less than 60 cm and a height of four or five times the width. Choosing a slender oval or rectangular mirror is based on the principle of reference, which makes people look slender: a slender mirror will visually make people feel longitudinally elongated, while a wide mirror will visually make people horizontally elongated.

2. Choose a mirror whose edge has a certain curvature. From the side, the mirror is shaped, or choose a slightly concave mirror in the market.

3, placed in a corner, placed at a certain angle, generally at an angle of 60 degrees to 75 degrees with the ground. The slender fitting room is tilted on the ground. Tall or fat customers want to see the full-length portrait in the mirror, so they have to stand farther away, and the portrait will naturally become thinner. In addition, the mirror is tilted, and the slimming effect is more obvious. Mirrors tend to use the principles of reflection and refraction of light. The visual effect of people is that the distant things are small and the near things are big, so if you look sideways, the people in the mirror will be elongated.

4. It is recommended to choose a fitting mirror with friction coating. A thicker silver coating will make the portrait clearer, but the price is higher than that of ordinary mirrors. The geographical thickness of the wave layer determines the quality of the mirror. If the coating is thicker, it will absorb less light and reflect more light, which will make the tone image fresher, but it will not repeat the wheel of the portrait in the tone.
