Pretty similar. Their hats were taller without a "rim" or "veil" down the back, and their sleeves were fitted. Also their "cassocks" were shorter than ankle length. I don't know the correct terms so I just used quotes, in case I'm using incorrect names
Not having seen them I can only guess, we don't really know who they were but if we go on the assumption that they were Orthodox for argument sake we can discuss it a bit. It is interesting.
I think most cassock type garments are called riassa, there may be other specific names for different styles, I don't know.
It sounds from the description like they might have been wearing inner cassocks (perfectly acceptable for street wear). This could account for the narrow sleeves.
I think that novices usually are only allowed to wear the inner cassock but all others may wear it too, and it would be under the billowy ones in the pictures.
Black generally indicates monastics, celibates. Married clergy wear similar clothing in white or even other colors, but avoid black because of the symbolism.
The individual with the pectoral cross on a chain would be a priest. If it is embroidered on, and really large, it could mean an advanced monk, like a schema monk (but I doubt it).
The hats with the rim on top (as in picture above) are common in Greek use, so these would not be Greek. Perhaps a Russian tradition, or Serbian.
These were not soft hats, I take it, but stiff and cyindrical, right? The hats really puzzle me, because they are taller hats it sounds like you are describing something like a fez and I don't know what to think. If they are soft and crushable they would be something like a skoufia, if they are cylindrical stiff with a flat top I think that could be a komilavka.
