A choir I belonged to previously had various costumes we used for concerts and travelling. When we were touring the U.K. we were late for an engagement after climbing Mount Snowden. We changed in the coach. Thank goodness we didn't have leggings.
On that same trip, we had to change in the gatekeepers lodge that might have held 15 comfortably. We were twice that number and changing into long, white dresses and cummerbunds. Oh just the thought of having to use that space and replicate the moves in the video below make we weep with laughter. Oh my!
