yes, they are imitations.
and no, it isn't right that the picture is titled "Melodia" ...probably in attempt to trick people into buying inferior goods. :(

oh i just saw those recently too~
it does make me angry when people blatantly rip off Melodia's designs, and there have been threads in the past discussing it, and it's just going to happen. :( and yes, the flared pant style has been around for ages, but Melo was the one who introduced them into the bellydance community, with her own pattern and style variations.
the best thing we can do is to get people to stay loyal to Melo and discourage buying of knockoffs.

though i know Melodia has said that she doesnt mind people using a special fabric they love and making their own pair of Melo-inspired pants....but they of course should not be making 20 pairs and selling them as faux-lodias.

from all the stuff i have ever read about imitation "dance flares" vs. Melodias, people more often than not favor Melos over anything else, saying that quality and fit is the the best considering the value, and generally get a bigger sense of satisfaction knowing they are supporting another dancer. :)

True Melos are awesome , Its just the feeling haha , of course you can buy those faux-lodias but think about it you will end up trying to fix them to fit you , but nothing can compare with the satisfaction of getting your loved melodias by mail and wear them for the first time ,they are great ...

I have made my own faux-lodias , since I am a seamstress and I like them but still I own 5 or more melos because they rule =)!!
