I am a very frequent wearer of Oxford and madras mens' button-down shirts (particularly from J. Crew; admittedly not the highest quality anymore, but they're relatively affordable compared to other upscale brands). I can't afford regular dry cleaning, so I clean my shirts using the washing machine and dryer. While in the past I've not had noticeable issues, I've recently noticed that the fabric in the collars of my shirts are fraying a little bit. I'm not sure what the problem is. I wash using the "colors" mode and dry using the "colors" mode as well (those are among the options on the machines in my building).
I'm sure I'm doing something wrong. Can you please let me know what the best way to wash / dry button-down shirts is, so that I keep the fabric and material intact?
