The core cast have not changed their cloths, since a scene that is probably at the end of 5.11. Whcih leads me to believe, that Emma and Gold reopened the portal to the Underworld and everyone went to save someone.

As for why part of the Underworld looks like Storybrooke.... 1. it is cheaper than building new sets. 2. Storybrooke is familiar to the audience. A&E have stated, that they regret setting most of 3.A in Neverland, because there was nothing to ground the arc. Storybrooke is what grounds the series in reality.
