My husband doesn't like how mantillas or hats look on me. Mass. It does the job well. Even for someone with slippery hair like mine, it stays in place better than a kerchief and, what's more, doesn't give me a headache. Since we go to daily Mass, I started putting it on in the morning and keeping it on all day. For me, it solved the Great Hair Problem which has tormented me since I married.
Some women are able to grow their hair long and pull it back.
So I woefully cut my hair short, which looks neater, but is awfully boring, particularly when you want to dress up, and still gets messy and flat from time to time, requiring mousse and a curling iron to look nice. The Hair Net, ladies, solved these problems for me. You can put it on over greasy, flat hair that you don't have time to wash, you can cover up wet hair that was just washed right before leaving for Mass, and you'll still look as neat and well-kept as a Mennonite nurse in her spotless white cap. You can dress it up by winding scarves around it or pinning it with decorative pins and artificial flowers. You only need to adjust it once or twice a day to keep it neat.
