Mormon missionaries will now be allowed to wear certain styles of sunglasses and hats, thanks to a recent update on their very strict dress code.

The amendment for proselytizers for The Church of Jesus Christ of Latter-day Saints was made to protect them from the sun during the hours they spend outside for their work.

But just like every section in the dress code, there are strict guidelines in what kind of hats and sunglasses the missionaries can now wear.

The Church of Jesus Christ of Latter-day Saints has an extensive list of dress guidelines for both 'Elders' and 'Sisters', including everything from outerwear and underwear - and everything in between

Sunglasses cannot have bright-colored rims or mirrored lenses and should never be worn when a missionary is speaking with others or is indoors, the guidelines read.

Fleece and knit hats are 'generally' acceptable in cold weather, and wide-brimmed hats can be worn in the summer.

But bright colored hats or hats that are 'too casual' are not permitted as they may distract from the missionary's message.

Banned hats include baseball, cowboy, bucket, newsboy and fedora hats.

Dane Zidek, who is preparing to serve a mission for the church, said he can see hats 'doing well' in places are really 'really sunny and hot', he told Fox 13 Now.

But Zidek was surprised to hear that sunglasses were permitted.

'I didn't really see that coming,' he said.

The Church of Jesus Christ of Latter-day Saints has an extensive list of dress guidelines for both 'Elders' and 'Sisters' on their website.

'As an ambassador of the Lord, you are to wear professional, conservative clothing that is consistent with your sacred calling and that will clearly identify you as a missionary,' the site reads.

‘Appropriate grooming will help you earn respect and trust...Never allow your appearance or your behavior to draw attention away from your message or your calling.'

Men are only allowed to wear white dress shirts when they are proselytizing and can never sport a skinny tie or bow tie.

The 'sisters' are not allowed to wear clothing that could draw attention to 'any part of the body'. Instead, their wardrobe must be 'dignified, clean, well-groomed, feminine and professional.'

They are not allowed to wear T-shirts or sweatshirts, unless they are exercising, and are never permitted to wear pants.

Their bras must always be white or cream-colored and earrings cannot hang longer than one inch below the earlobe.
