Curtain questions

I am considering getting a set of curtains for my 2nd Gen GS430.  

[B]Concerns:[/B] I know people have had issues with sun damage and fading.  I have stock tint but my car is hardly even in direct sunlight.  I park in a parking garage everyday and my car sleeps in a garage at my house. So I'm not to worried.  Any comments

[B]Size:[/B] Is a small (390mm) to small[B]? [/B] Should I go with a medium (450mm).   Will I need a different size for the rear seat window[B]?[/B]

[B]Brand:[/B]  Any specific brand[B]?[/B] I don't want them to be super translucent.  and if I pull them I don't want them to be flat.  I still want the creases.  (here is a pic of what I am talking about) 

I like when you pull the Garson curtains they still have the creases

small is perfect.  there curtain belt looks sick.

same size front and rear side windows?

Any fading color tips?

Don't roll your windows done when it's sunny!
(Seriously!)
