To wear pantyhose, or not to wear pantyhose, that is the question.
Women the world over are torn between sporting the itchy, easily-torn accessories or going out bare-legged. While pantyhose may not be the most comfortable part of an outfit, they do bring an element of sophistication to an otherwise semi-formal ensemble.
While most young women agree that pantyhose are outdated, there are certain occasions -- mostly conservative -- when wearing pantyhose can be appropriate. While it's generally considered appropriate to be bare-legged in many work places, it's still a good idea to wear pantyhose for the interview.
This is because you want to make a good first impression and the person interviewing you may be much older. Because pantyhose are generally considered old-fashioned, if you are bare legged your interviewer may unintentionally misjudge you based on what she considers to be your inappropriate attire.
When attending church or temple, it's always a good rule of thumb to be as conservative as possible. While it's usually completely acceptable to wear formal slacks to church, you can also wear skirts with pantyhose.
Pantyhose aren't necessarily required, but they do add an element of formality that lacks in skirts without pantyhose. You should especially consider wearing pantyhose when attending church with people you are less familiar with -- such Women wearing blue pantyhose your in-laws or your friends' family. Whether it be an award ceremony put on by your co-workers, a first communion, a wedding or a funeral, pantyhose are the way to go.
Again, pantyhose takes a dress to a level of conservatism that can't otherwise be achieved by a skirt alone. During highly formal ceremonies, it's always safer to be overdressed than underdressed.
