Looking for sources that sell plus size Dancewear approx. size 18 to 20.

Are you looking for practic wear or a comp dress?

Comp for American Rhythm and Smooth.

There are some large size dresses over on Encore Ballroom Couture. All the dresses are done in Swarvoski stones. http://www.EncoreBallroomCouture.com

I have a burgundy smooth gown by Kelly Kealy Mayton. (She designed a costume for Derick and his partner one time on Dancing with the Stars.) This dress is COVERED in dark red Swarvoski stones. It comes with Swarvoski earrings, a Swarvoski encrusted collar necklace and the KK travel bag. - I'm 5' 10". I've not sent this dress to Encore yet. Let me know if you would like more info on this dress.

I was wondering if you still have the dress you referred to in the post to tbelan?

Do you prefer any specific colors? Do you need sleeves? Do you like fringes? I can post a few pic for you if you are interested.
