Ok. I was told that for RonRon sizing, thanks to Sakura!!

:
I own the SS '09 Turquoise Suede RonRons (which I bought in a 37) and that anything from FW '09 or later should be approximately my TTS size 36.5.
So, I'm having a mini panic. I JUST purchased the Lilac (Lavender?!) suede Ron Rons off ebay and I'm scared...are those from SS '09 too??!!? Can anyone confirm their season/year?
I got them 1/2 smaller than my TTS (36 cause I'm apparently crazy) and I'm already sure they will be tight but now I'm afraid they will be unwearablely tight!!
Perhaps I need some kind of comfort or assurance they just MIGHT fit????
