And as for wearing the same clothes for 2 years, that actually makes sense for Elsa. Her Dress is really just an extension of her magic. It's not just what she wears, it's actually who she is.

I always envisioned the Snow Queen (and by extension Elsa) to be clothed in what essentially amounts to flowing Ice. The ice crystals are what provides the shimmering effect. Obviously a magical material. And being Ice, the ice melts (or sublimates) as it hits the warm air, meaning new crystals are formed to replace the old ones. So her outfit is constantly changing.

For SB, they could have achieved a similar effect by having the dress change appearace, to more like light blue denim slacks and a light blue sweater. In fact, I would probably have shown Elsa magically changing her appearance, just to reinforce the notion that her clothing is an extension of her magic. But i guess, for as short of a time as I am sure the time flow will be internally, staying in the same dress is OK. It's not like she's going to be dressed that way for 11 weeks. who knows, they might get this arc done in time for Elsa to catch the opening premier of Frozen. :)
