Heels or better shoes with heels are designed to have heels. That sounds like an open door but it’s crucial to the design of that sort of shoes. Slippers, sneakers, loafers and other types of shoes are designed without heels or destined to have at most a heel of an inch.
But flats…. that’s a heel without a heel, a cheap solution for a design problem. Just leaving out the most essential part of a well designed, beautiful and stylish shoe can never result in something beautiful or functional for that matter.
It just doesn’t work, it’s not acceptable, don’t make them, don’t wear them.  
 
The only exception perhaps are boots…. They can work with or without a heel… but otherwise; stay away from flats. 

I understand that hair needs to be trimmed, tamed even, sometimes needs to be removed or permanently eradicated. Humans – both men and women - have a long history of growing, removing or trimming facial hair, cut, extend, perm and paint hair on top of our heads, not to mention hair removal on arms, legs, backs and other body parts or pubic topiary.
But the reason behind removing eyebrows and replacing them with an embroided version is alien to me. If you have no eyebrows (anymore) I can understand you’re looking for a solution, but if you have eyebrows, I don’t see the point removing these and replacing them with an artificial alternative.
More and more people seem to find this interesting, useful and beautiful, not only women but also men, young and old. Maybe it’s a trend, maybe a hype but to me it makes no sense, are there really no bigger causes in this world, no more meaningful things to worry about than your eyebrows?
