I really do not care for any of their's minus Daphne's ; but, probably Bloom's since her kind of just looks like cotton candy all dried up just my opinion though

I kinda don't like Musa's and Stella's Sirenix that much. The others' Sirenix are good in my opinion.

Bloom's Sirenix does not fit her at all. The blue clashes with the red and the result is: horrible

Musa's is tacky and tasteless . I see hers as a red fish with wings. Considering her normal look too it seems way too girly. Terrible.

Doesn't go with her hair.

@zikkiiforver: Musa's outfit is NOT horrible. Red and green go well together.

Bloom is my favorite, but even I have to agree that this outfit is terrible.

Blooms is just awful, it looks horrible with her hair.

Flora is so totally going next.

It just doesn't suit her ;)

@DarketLOOP I must say red and green go well together ,but it is not the colours it is how it looks on her. I just find it bad.

Bloom's Sirenix is awful! I don't like the way her pants, top, and shoes are.

I wonder what the Winx designers were thinking when they made Bloom's Sirenix. They want Bloom to look the best yet they make her look horrible.

Her hair, is fucking ridiculous. Bloom's sucks too.

Daphne's hair isn't bad, sure the loose strand in the middle of her face drives me crazy but I think she's beautiful!

The two patches on the side of her face look ridiculous.

Don't really like her's at all.

I LIKE DAPHNE!AND I DON'T THINK DAPHNE HAIR SO BAD.

Horrible hair
