Thanks for your feedback and honest reply. Here my thougths:
About "Fear of ridicule" : there are better cape - options than the one shown in your picture.
If you happen to do not like capes at all anyhow, than there seems to be no problem : do not want it and don't do it.
Tastes differ, also about what is fashionable and what not. No problem, that 's part of reality.
Apart from wearing capes is my opinion is that you have to wear clothes where you feel comfortable and good in.
Why wearing capes if you do not like them ? If so : Do not do it. Keep them reserved for your Halloweenparty.
If it is because capes are not "practical" you are probably rigth.
A coat is easier in use, though there are even capes with pockets inside.
But if "practicality" is the only standard then let's forget about a lot of accesoires : the hat, the tie, the pochet etc. : not practical either.
Just use jeans and t-shirts. And feel good about it. No problem. If it only has to be practical.
But if you happen to do "like capes", and never have weared one : so stay at the safe side to begin with.
Here is my advice :
Choose a classical one ( black or darkblue knee - length ) and combine it well.( Have a look at the pictures above)
Ask your best friend or girl friend his or her opinion for feedback
And finally have your try out and go together for a nice coffee in town on a terrace.
Enjoy your company, enjoy your cape, enjoy your day and discover perhaps something new about your own taste and style.
