Input (English): [header] How to buy sunglasses [title] Choose a frame shape that contrasts with your face shape. [step] That way your sunglasses will balance out your face when you're wearing them. Wearing frames that match your face shape may accentuate the shape of your face, and they won't pop as much. <sep> (A) [substeps] Choose frames that are either rectangle or triangular, as long as they fit comfortably. A rectangle frame is the best, as it's long enough that you won't have to carry the frame across your face when you come in. (B) [substeps] Frames made from leather or polyester must match your skin tone. A frame made of glass works best because it won't pop as easily on dark eyes. (C) [substeps] For example, if your face is more round, you could choose a pair of square, angular frames as a nice contrast. If you have a squarer face with a defined jaw, sunglasses with round frames may help soften the angles of your face. (D) [substeps] If you have long hair, you may want a frame that is slightly taller than you. You can also consider a frame shape that matches the shape of your face.
