Where to Find an '80s-Style White Shirt for My Vintage Armani Suit?

I have a three-piece black pinstripe Armani suit from the '80s/'90s, and I’d like to pair it with a nice white shirt. Specifically, I’m looking for a shirt that matches the style of the '80s long, narrow collars and designed to work with a very slim tie knot.

The problem is, I’m not sure where to find a shirt like this. Does anyone have any suggestions or know where I can look? Retro clothing stores, vintage shops, or even modern brands that might reproduce this style. I'm open to all options!
