SNAPPY SOLDIER TUNIC PLEAT

[Tarbicus]

I would like to see some pictures of non-military tunics with the pleats. Somewhere in this thread, either Bishop or Sumner has pointed out that the depiction of pleating on the lower part of the tunic appears mostly in steles from the Mainz area.

Here's what I found in the Imagebase, and they do seem predominantly from Germany.
Publius Flavoleius Cordus - Mainz
Gaius Faltonius Secundus - Mainz
Genialis - Mainz
Unknown Miles - Mainz
Unknown Miles - Mainz
Quintus Petilius Secundus - Bonn
Firmus - Andernach
Hyperanor - Bingen-Bingerbrück
Tiberius Iulius Abdes Pantera - Bingen-Bingerbrück
Pintaius - Bonn
Unknown Miles - Cologne
Apart from those with date unknown they are also 1st Century.

Less definite and outside of Germany:
Balaterus - Cherchel, Algeria
Camomile Street Soldier - London - my favourite and done by an incredibly talented sculptor.

but I think that the u-shaped pleats may just be a natural product of the short tunic, regardless of context.

It's definitely a natural effect of gathering and hitching the tunic up to shorter length.
