Re: with a T-shirt
Not if you're female and avoiding arrest. :)
It was so nice here on Sunday that I went for a walk, and ended up taking off my sweatshirt and walking in just my t-shirt (on top, of course - I was also fully clothed and shod from the waist down). For November, to just be in short-sleeves was amazing.
Illogically, we also use "in bare feet" in the US. "I can't believe you ran out there in just your bare feet." Or "You can't come in here in your bare feet. Put some shoes on."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
