Here's our first official look of the title character.

She looks atrocious.

This is an utter failure of a design, even without comparing it to the original. First of, she doesn't even look like a woman; she looks like a teenage boy. It's one thing to make a female character physically strong and athletic, it's another to completely remove any signs of her occupying a female body. For example, Korra from The Legend of Korra was athletic and had muscular arms but you could still tell she was a girl based on her anatomy and facial structure. That's not the case here. Remove the long hair (which doesn't even look like it's attached to her head; it looks more like a yellow mass flowing behind her) and not a single person would get that this character is supposed to be female. You don't need to sexualize a character or present them as overtly feminine to get across they're female but completely ignoring the physical traits of the female form is preposterous and sexist. This would be a poor design even for a male character but the fact it's for a female one makes it a complete and unmitigated disaster of a design.
Another issue I have with the design is the bike shorts she's wearing underneath her dress. If you believe her dress is too revealing just make it longer or if you want her costume to be more practical and efficient then just give her full-length pants or an armor. But giving her both a dress and bike shorts is unappealing, anachronistic, and nonsensical. It defeats the purpose of wearing a dress. Women wear bike shorts underneath their skirts for sociological reasons (skirts being mandatory as part of a uniform, modesty culture, afraid of being leered at or harassed etc.) none of which apply to She-Ra.
