Hello fellow Saints, I’m a 24-year-old male church member, getting endowed soon. Since I never in my life liked waistbands, I think I would prefer wearing one-piece garments.
In terms of size, how do I know which size shall I order online? As far as I know, this kind of garment can only be bought through the website…
I’m 5’9’’ and slim.
