This could go in DIY thread but I'd like the "advice" part on PC jacket collar style first.

Recently jumped on a thrift store find, perfect fit tuxedo jacket (and pants, to supply material for patches, possible vest) destined for a PC conversion project.

It hit me later that this jacket may not be the best place to start. It's got a shawl collar, with a thin black satin border (and matching satin stripe up the trouser legs). Photo below (the spots are just artifacts, not on the jacket).

Would a quasi-PC with shawl collar just look too silly? I could attempt to create a notch in the collar, and use the trouser stripes to miter in the satin border, but obviously that's a lot of fiddly hand work and satin is not the most forgiving fabric. Afraid I might bungle it and have ruined the whole thing.

Thanks for your considered thoughts.
