I just updated the Alpha with TopsMaleSpandex for your dressing pleasure.
A note about how these work. Inspired by something Mark Shute did in HM2.x, I have a set of base spandex tops with sleeves of varying lengths. Think of these as your "base" tops. You can then layer (using the "Multiples" setting) the other pieces over it to create shirts of different types. For instance, you could have a short-sleeve shirt with a deep V neck, or a scoop neck, by swapping out which neck piece you use. You could even color the neck piece the skin colors to make it look like it's part of the character's body.
I've only played around with it a bit, but it's a very subtly powerful way to create. By mixing and matching the pieces you can make some really varied effects; I look forward to seeing what you all come up with.
As usual, let me know any items you would like, but don't see, or any bugs you come across.
Eventually I'll flesh out the Tops slot with more expanded sets like in 2.x, with Coats and Overshirt type items, but for now these two ought to give you a lot to work with.
Tomorrow I'll be adding any spandex tops I've forgotten, and then will move on to facial slots (Nose, Eyes, etc.). So holler if there's anything in that regard you want to see.
