It's not like it was a "kitchen knife" or anything.
I remember though that the template for his Avengers armor does have some open/uncovered spots to it, in particular, the sides of his waist are left completely vulnerable, though I can't remember where exactly Loki stabbed him.
Regarding his costume in general, I hope that Alan takes the best of both designs from his "Thor" and "The Avengers" look and melds them all into one since I have yet to see a Thor costume that has me completely won over.
