What looks fabulous on one person can look terrible on another. That is due in part on the size of your face and in part on the shape of your face. Your face shape does play a significant role in whether a frame will suit you. Generally speaking a square frame will suit a round face and a round frame works well with a square face. Many different eyeglass shapes will suit oval faces, including round, square, cat-eye or octagonal. Another face shape less common is the heart shape where the face has a wide top third and narrow bottom third. The ideal frame for this face shape would be a frame that is wider on the bottom.
More important than the lens size is the overall frame width and how it works with the width of your face. Not all 52 eye size frames will fit the same. Rather pay attention to where the end piece of the frame is in relation to your face. The end piece should match with the widest part of your face, which is generally at your temples (near the top part of your ears).
