I’m going for a charcoal-ish grey, which hopefully will look okay. I like monochrome. My only concern is it accentuating my chesty build, but I’ll just layer it up if it does.
On the topless shirts front, my brother Skyped us to say Merry Christmas and he was wearing a t-shirt the exact same colour as his skin, which made for a very confusing first couple of seconds, particularly as he was standing with his wife in his in-laws’ kitchen wearing a santa hat.
