Take it from someone who LIVES in Alaska. Believe it or not.... Alaska can get very warm here. It's only the winters that are cold like people believe. Although it is warm in the summer, it can also be rainy. So...... I would pack ...
~You can DEFINATELY get by with a hoodie
~shorts if you want
on formal nights
~a dress, but not a sundress.... a long one.
Like I said before, Alaska isn't REALLY cold until the winter months. It can be VERY pleasant in the summer. It is truly beautiful up here in the summer.
Hope I helped and have fun!
ps.... Alaskans live in HOUSES, not igloos. haha lol We do not have moose as pets, although they like to come into your yard!!
I have seen wolves, bald eagles, moose, bear (there was one around my school last year... scary!), and many other animals up here! So also pack a camera!
