This is a 150-size Chopin dress purchased 3 days ago for a piano recital! The collar is removable! It's perfect for recitals with the sparkly ribbon, and also for graduation ceremonies! Removing the sparkly collar makes it suitable for formal occasions, which is convenient! It was only worn for about 2 hours once, so there are no stains or frays, and it has been dry-cleaned, so it's in excellent condition!
