Brass scale armour (Lorica Squamata)- With Doublet 

A type of cuirass was the lorica squamata, also known as scaled or jezeraint armour. Scale armour is perhaps the oldest type of metal body armour. Peterson proposed that its origins date to at least the 2nd millennium B.C., having a long history of use in Greece and the East. Despite its early origins it was used throughout the entire period of Roman dominance. Scale armour is usually depicted with short sleeves.
