I unironically really like that white dress she's got in her last post.
If you mean the outfit with the school blazer: the dress or skirt looks a lot like this skirt from Armedangels:
You can't see it well in this photo, but it has slits exactly in the same spot as Ruby's skirt and it's the same length. It's called the Katinkaa cream skirt. It's from a previous collection but you can still find it second hand online.
