My mind immediately pictured a white cycling outfit from ~1912 with big bloomers, a boater hat with a ribbon hanging down the back, and a sailor collar with a big navy tie in the front. Something like
this but in white with a boater hat. Definitely "wacky" by today's standards but quite fashionably edgy 100 years ago. When this is over, I hep the OP shares a picture of the real wacky outfits that are traditional for this chapter!
So… will the OP be climbing a Stairway To Heaven wearing a wacky outfit with sisters whom she aspires to be like? Or will she be Just Another Brick In The Wall with sisters who seem more like her now?
