1980’s Beverly Hills Polo Club polo in pink, purple & yellow. Very fairy kei! In good vintage condition, definitely some wash wear. No size is legible inside but here are the measurements while lying flat:

24 inches pit to pit

28 inches from top to bottom

this would fit a modern day large or XL depending on the look you're going for.

This item is sold from an excellent, highly rated vintage boutique in New Haven, CT.
