Clothing can be a clue to C of E clergy.
Button down shirts and chinos is the uniform of the mega church charismatic evangelicals. If they own a clerical collar it will be pale blue and only worn at funerals. Most charismatic evangelical incumbents (usually called senior pastors like their American colleagues) are male. The women who are usually assistant clergy or wives, are a more diverse group and may wear a clergy collar under street clothes or they may be indistinguishable from the laity like their male counterparts.
Conservative evangelical clergy are male and may well be in a suit rather than smart casual. If they are wearing a clerical collar it could well be a full one rather than one of the tab collars.
Parish clergy who are found in smaller and/or rural parishes will often wear a clerical collar and may well be in all, or mostly black. If you have seven churches, three schools and four villages that haven't spoken to each other since the civil war then having everything in black saves time first thing in the morning.
Parish clergy need to be identified as clergy as they are there for the whole parish. Mega church clergy have churches where people travel for that style of worship so they are less concerned about being known in the geographical parish.
There are some niche variations. Some male clergy wear cassocks around the parish like Father Brown. They are probably traditional Catholics who do not affirm the ministry of women and would be over to Rome if wasn't for the rules on celibacy.
Bishops can usually be spotted wearing a cerise colour although some do wear black. The give away if they are in black is that they wear a big cross on a chain (pectoral cross) and a ring with an amethyst in it. They are usually accompanied by a chaplain who is chivvying them onto their next appointment. If you find a stray bishop please take them to the nearest coffee shop, feed them cake and tell the Diocesean offices where you found them. They are doing an impossible task trying to work through the impossible task of church unity so caffeine and cake and a nice chat will cheer them up immensely.
