Some basic questions

[Caballo]

First, welcome!

Second, I'm assuming that you are looking to recreate a first century Roman group?

Linen was worn, and a first century tunic is dead easy- basically a large rectangle doubled with openings for neck, and arms ( and legs of course.) . Best source will depend on where you are.

Yes, please wear a subarmalis under a seggie-this will get the "sit" of the armour right.

And, yes, bracelets can be worn.

Have fun!

Cheers
