Help me understand this website.
Apparently Make Your Garments dot com is a site that screen prints garments on any underwear for members who can’t wear traditional garments. Yet on the page I referenced, it clearly states this site is not affiliated with Beehive Clothing in any way and says that if you are attending the temple it is best to wear regular garments.
Does this mean Make Your Garments is a scam/joke/weird thing? I am intrigued by the idea that some people just don’t fit into traditional garments (enough women on the internet complain about it you would think everyone is suffering from bunched up, power weggies all day long) and that this an option for them. But really? What is this?
