I am not in my twenties and more, but *think* I am pretty hip. I think the shawl you linked to is pretty and modern looking. I agree with the grays... always a good choice. I also like purpley-gray colors. Cream (or other light colors) with babies is never practical. I would skip the sparkles.
Editing to add: I think this would also be a great spring/summer wrap in a hemp or linen
PS. I bookmarked that pattern and I am generally not the shawl-type.
