Born and raised in Austin, I can tell you this is the best costume store for over 30 years in all of Austin. I rented from here for so many parties I went to.
Lucy's has been our families go to for costumes. We have found the most unique costumes for Renaissance festival, Halloween parties and also rental of big head costumes for birthday parties. They are a year round costume shop and a must stop on South Congress even if you are not looking for a costume. It is just a fun spot to go and explore.
