I'm tempted to swap the buttons on this 80's era RL blazer I own. I feel like it will make it have more of the traditional navy blazer look. However I'm also of the mindset "if it ain't broke don't fix it". The gold buttons are RL as well. Would be great to hear some additional opinions from you guys.
I say go for it. It's a fun, classic touch, and if you decide you don't like it it's just about the most easily reversible modification imaginable.
