How do I poof my elf skirt?

You could make a tierred petticoat with fabric, I found these instructions that are for a longer version but you could make it what ever length you would like. I find tulle seems to catch alot on certain fabrics when you use it as a petticoat but with regular fabric it won’t catch however it will be more time consuming and costly to make.

Tulle may have been too puffy. Try netting gathered at the waist with elastic. The velvet skirt doesn’t look like could handle a lot of bulk under it..

You look totally adorable in that outfit! Do you play the accordian?
You will not be able to puff the skirt out much because it’s not that full. When you see the puffy skirts they are usually circle skirts and then you wear a very full petticoat (what you call a tutu) underneath to make it stand out. I’m not sure how full your tutu was but something like this might work.

Thanks for the helpful answers, all! @creative1 Good call, the tulle is super catchy. @Sunny2 It is certainly heavy, so I am worried about that. @Earthgirl I do play the accordion! Thanks! It’ll be even better with the new elf shoes and hat I’m working on :) I might just re-make the skirt to be a circle, I’m sure I can find more of the fabric.

Off to work!

I’ll poof it for you. ;-) I got the lungs of a trumpet player!

Cute outfit :)

Have you seen those soft, super-poofy slips that they use for clogging or square dancing? I think that would work.
