How to wear a fascinator
Coordinate the size with your hair style.
If you want to wear a fascinator with your hair slicked back, then go with a smaller one. If you're going to wear your hair loosely pulled up, then a medium size is probably best.
Wear a large fascinator if you're wearing your hair down and in a voluminous style. Pick the material based on the season.
