'Half tutus' otherwise known as 'bustle tutus' are great for both kinds of people.
The kind of people who want to go all out with their costume. Get the legs out and strut your stuff!
Or the people who are being forced to dress up. (What? This happens?)
With bustle tutus you can either go crazy and wear with little hot pants for a sexy look or add on top of leggings or even jeans. So you're dressed up but you're still feeling comfortable!
