Yes they can. As a Christian I wear pants myself. But, God doesn't judge you or anyone else by their outside appearance. God looks at the heart.It's your choice really if you want to or not.
People wear trouser socks for various reasons. One common reason
for wearing them is for the sake of appearance. Trouser socks are
designed to compliment a more formal pair of pants. People may also
opt to wear trouser socks due to the sheer comfort of them.
There are many places online to get a trouser rack. You can go
