Roman Tunic - Help

[Martin Moser]

On Republican togas it would be sewn only on the rounded part (sinus), sewn because it is not possible to dye a rounded edge equally.

Hm, interesting - I never dove into togae in any kind of detail. Is this personal conjecture or is there research you are basing this on? Are there any finds attributed to a toga, btw? I never heard of any myself ...
As later tunics show e.g. details were woven in in any number of shapes. Then there also is resist dyeing, although I have only seen Coptic/late Roman examples so far and I think they all were on linen rather than wool.
