Widget alignment and RTL

Dears, thanks for the awesome template. My blog is bi-lingual, but mostly in an RTL language. How can I change the widgets (in a single, right-sidebar layout) to be aligned to right and correct RTL? Bonus would be how I can do it for each widget separately? e.g., since the archive widget lists the month names in english, I want it to be LTR. But Recent Posts to be RTL and aligned right. Thanks
