What is the christian dresscode?

theres no evidence in the bible that guide you SPECIFICLY how you should wear your clothes. In islam, it is made specific that only our hands and faces should show. No showing the SHAPE of your body and not even your hair. Why cover the hair? Because if you had to cut off a hair of a girl, she wouldn't like it..she'd probably go crazy without her hair because our hair is our beauty that compliments our face thats why girls care what style they'd like in their hair. Thats why we should cover our hair to guard our modesty cos men look on the appearance while Allah looks at the heart. Ever heard men on the streets giving you sexual remarks like 'hey sexy' 'nice back off' those sorta remarks? Y'know why? Cos they are perverts and they see what you reveal to them-your shape of your body and hair. So why do majority of christians wear clothes that doesn't fully cover up?? You can say well our face is our beauty as well but the reason we dont cover our faces is cos we need it to show our expression! So dont try using that in your argument. TAKE A LOOK AT THE NUNS HOW THEY COVER UP PROPERLY. Why their dresscode so similar to islam?
