Yes, it's another library themed lookbook. I promise I just stumbled upon it by happenstance - I was admiring the work of Bea Szenfeld via a post I found on White Lightning. She was discussing Szenfeld's more recent work, but on the designer's website I scrolled down and found a prior collection which I loved even more.
Even though I love all of it, I think the paper bow tie and the alphabet mask might be my favourites. This collection maybe be a couple of years old now, but it is just as fresh, at least in my mind as it would have been when initially released. You can read about the interesting inspiration behind the collection here.
