Just experience doesn't change anything, it's only used for promotions. You can double click to get all units of the same type and if you triple click you can limit the selection to the same rank. Generally micro isn't of much relevance until you become really really good at the game, so I'd suggest to focus on macro instead.

When I play, I often (after a battle) try to select all of the soldiers with high experience. It always takes a big amount of time which often also results in me losing. So do we have a hotkey for this or should I simply just not try it because it takes so much time?

It's definitely a cross between Roman clothing and Parthian. Valerian and Shapur I look quite similar.

Banquet reliefs at Palmyra often depict young men in attendance dressed in almost identical outfits to their master. Their costume consists of a belted roundnecked, long-sleeved tunic with a decorative band on the neckline, cuffs and hemline, a cloak, tight trousers.

Parthian fashion, especially Hatra's, influenced Palmyra's style...The_Parthian_haute_couture_at_Palmyra.pdf   --- The document analyzes how the dress of Parthian origin (Iranian) became a symbol of prestige among the elites of Palmyra during the I-III centuries AD, despite the fact that the city belonged politically to the Roman Empire. The author argues that this fashion arrived thanks to the intense commercial contacts between Palmyra and Parthian Mesopotamia, and that its use reflected wealth, prestige and cultural identity more than a political affiliation suit are also known from late Parthian-period reliefs and statues in Iran and Mesopotamia. In Elymais in southwestern Iran a long-sleeved long sash is often worn in addition over the left shoulder. 10 The art of the semi-independent kingdom of Hatra has also produced many examples of the trouser-suit (fig. 5). Here, male worshippers and some of the gods wear elaborately decorated belted tunics which are combined with baggy trousers. Floral and geometric designs running down the centre of the tunic and the At Palmyra there are many funerary and religious reliefs – and some statues – showing male figures dressed in the Parthian fashion. In addition, actual finds of textile fragments from Palmyrene tombs suggest that in the first to third centuries AD a large part of the population adopted the Parthian fashion, while others were dressed in the Roman style of the time. 12 The trouser-suit at Palmyra consisted of a round-necked long-sleeved belted tunic – short, knee-length and long trousers and/or leggings. Often a cloak fastened on the shoulder was worn, or a himation was draped.   An early example of the Parthian costume occurs on the architectural reliefs of the Temple of Bel. 14 The ‘Foundation T’ relief shows a headless rider figure looking right and wearing a round-necked (?) longsleeved belted tunic, a shoulder cloak and wide trousers/leggings (fig. 6). A decorative vertical band with dots (pearls?) runs down the side of the trouser leg. A similar (divine?) rider figure, but turning left, wears an almost identical outfit with a decorative cable pattern band on the side of the trouser leg. 15 Relief decoration on the stone beams of the Bel Temple shows that trousers were also used to dress divine beings. For example, the god Aglibol wears a long-sleeved tunic with a cuirass, a cloak and wide leggings with the ornamental band at the side of the trouser legs rather than in the centre (fig. 7a). Wide leggings with diagonal folds fall over his shoes. The leggings were probably attached to suspenders covered by the tunic and were pulled up at the outside of the thighs. 16 On the so-called ‘Offering scene’ of the Bel Temple male figures wear a draped himation over long tunics. The legs of two figures on the left are covered with leggings/trousers (fig. 7b). Trousers are also worn on a late first century altar relief from the sanctuary of Baalshamin. Here, the god Malakbel appears with a bushy curly Parthian hairstyle, 17 and next to Malakbel and his chariot stands a dedicant wearing a long sleeved tunic, a draped himation and wide trousers.     The funerary art of Palmyra also provides us with many examples of male figures dressed in tunics and trousers. 24 A relief from the tower tomb of Kitôt in the Valley of the Tombs of AD 40 shows the principal reclining figure in the presence of his wife and two sons. Kitôt wears a long-sleeved round-necked tunic, a draped himation and wide trousers with a decorative band; traces of greenish/blue colour were discovered on his trousers. 25 A draped himation over the tunic is male figures, probably priests, at Hatra and Dura Europos during the second and third centuries AD. 27 Banquet reliefs at Palmyra often depict young men in attendance dressed in almost identical outfits to their master. Their costume consists of a belted roundnecked, long-sleeved tunic with a decorative band on the neckline, cuffs and hemline, a cloak, tight trousers 26. Curtis 1993, pl. XXIb. ---These also catch my eye.--- Perhaps the pants should look looser. I made these but they should wear pants or trousers. At least I know that the garment worn over the main robe has a name and has already been mentioned several times. Himation (rectangular woolen mantle that was draped over the chiton, much like the simlah or me'il). Philosophers, teachers and elders were frequently represented with this combination.
