MADELINE: There’s this great store under my therapist’s office who has the best vintage clothes. I found an original Pucci top for practically nothing.
LOUISE: Oh Pucci is very big right now.
Pucci is an Italian fashion brand originally founded by Emilio Pucci (1914-1992). Pucci clothing is synonymous with stretch-knit clothing in bright, geometric designs, and when Madeline says she found an original Pucci top in a vintage store, she means one that would have been designed by Emilio Pucci himself.
There are quite a number of vintage clothing stores in Hartford where Madeline might have found the top, but it seems unlikely they would sell an original Pucci top for “practically nothing” (the one in the picture costs nearly $200 today). She got very lucky that day.
We also discover from Madeline’s casual statement that she regularly sees a therapist. This might come as a surprise, as Madeline seems to be very cheerful and unconflicted by nature, but perhaps that’s because of all the therapy?
