Mormons believe in being modest. Our bodies are gifts from our Heavenly Father, and we believe that they should be treated as such in every way. The way we dress is a reflection of who we are on the inside and influences the way you and others act. This is why Mormons are counseled to dress modestly.
Girls are encouraged to avoid short shorts and skirts, tight-fitting clothing, shirts that don’t cover the shoulders or stomach, or that are low-cut in the front or back. Though usually not an issue for guys, they are also encouraged to maintain modesty in their appearance. In the For Strength of Youth pamphlet, it states:
Never lower your dress standards for any occasion. Doing so sends the message that you are using your body to get attention and approval and that modesty is important only when it is convenient.
It is not always easy to dress modestly, especially on occasions where there is not a lot of modest options available, such as formal dresses and swimsuits for women. Mormon women, young and old, do what they can to work out modest options, such as adding sweaters to sleeveless dresses or finding modest swimsuits from specialty stores.
Not only do Mormons feel like being modest is important, but also looking clean and presentable, in general. We are also encouraged to avoid extremes in clothing, appearance, and hairstyles. The pamphlet also states,
Do not disfigure yourself with tattoos or body piercings. If girls or women desire to have their ears pierced, they are encouraged to wear only one pair of modest earrings.
Dressing modestly is a way to show respect and gratitude to the Lord for the bodies that He created.
