Tell me why---Please

Would someone please tell me why a female would wear pants and shoes that make her look fat? No mirrors around?
Would someone please tell me why an older woman would wear a dress out that makes her look like she is trying to be 6 again? No mirrors around?
Would someone please tell me why a very young actress dresses more like my grandma than my grandma does? No mirrors around?

Obviously being known is not having taste.
