I'm into Antiques now...
It does sound very camp when I wrote it..
I've got like 30 myself, but a lot of it is because I travel between places a lot. I think you can have linen rotation for summer/hotter weather and then your sea island for more formal settings, and it's just fine. I personally have a bunch of inexpensive egyptian cotton twill shirts that I am extremely fond of and plan on getting a few more soon.
I definitely have a couple too many bold shirts though, but that's partially an age thing I imagine, but now I feel like I am growing out of it. Hard to wear my dark navy or burgundy or striped shirt with a jacket. Think these look fine with jeans and in casualwear but I just don't dress like that much anymore so they don't get much wear. I still think they look nice though, so eh, whatever.
