The current exhibit in the museum is Fashioning Philadelphia, which runs through June. This collection is based on a book (I forget the title!) where a woman essentially falls from grace, evidenced in the collection with the reddening of wigs and less clothing providing less and less coverage.
And it’s only $5 to get in the museum to see it!
These pictures don’t show everything, just my favorite parts :)
P.S. - In the last 2 shots, the yellow door on the left is where you come out after you finish the tour of the museum house.
