It's part of her character. She's from a planet where the cultural norms of nudity and sexuality are very different, so she sees no reason to cover up. And she's a character who represents sex-positivity. She sees sex and nudity as things which are good and not shameful, and while obviously you or I wouldn't walk around dressed like she does, I think she sends an important message. I'm not in favor of superheroines being in skimpy costumes just for its own sake, but with Starfire I like it because it's character-driven.
Sorry for the mini-rant there. It's just... I love Starfire, and I hate that she gets called names like 'skanky' and 'slutty' because of her costume. First of all because no woman should have to put up with being called names because of how she dresses, but also because Starfire happens to be an awesome character who's so much more than her costume. She's an INCREDIBLY strong powerhouse (like, seriously... Superman-level powerful), she lived through years of slavery and dehumanization and survived, she's the kindest and most caring friend you can imagine, she's a sweetheart even to total strangers, she's confident and comfortable with herself but not arrogant, she's passionate and strong and she always stands up for what she believes in even when that's not a popular opinion. And yeah, she wears a skimpy costume because she was raised to see no problem with that. But there are so many more important things to love about her character.
i actually just think the men who creating her wanted to justify why they made her a very exposed character you have to remember these characters are all designed by men, for men so they know that's what men will buy no woman in their right mind would enjoy walking around in what she wears, let alone having breasts that big (so many woman heroes have extremely disproportioned bodies)
Except that isn't true. There are plenty of cultures even on this world where walking around in next to nothing is the norm. Specifically in hot-climated places like Africa, and Starfire is from a desert planet. It's not unrealistic at all that less clothing might be the norm there. Modesty is a very cultural thing. There have been cultures where seeing a woman's wrist was considered scandalous, and there are cultures where being nude is totally acceptable. People in their 'right mind' will enjoy wearing whatever is considered normal in their culture, and Starfire is no different.
Is there an element of fanservice to her character? Sure. But bear in mind, her creators were the same people who created Raven, a character generally covered head-to-toe with robes. They also created Cyborg, who was pretty scantily-clad for a male hero: [link]
What was great about the original New Teen Titans comics is that there was fanservice, but (a) they were very equal-opportunity about it, and (b) it was character-driven. Starfire would be very relaxed about things like nudity because that fit her background and personality, but other female characters (like Raven) would be treated very differently. And even more tellingly, when the other Titans visited Starfire's planet, the men of her culture were shown to be dressed just as scantily as the women: [link]
And more tellingly yet, the creators had Robin dressing the same way to fit into Starfire's culture while they were on Tamaran: [link]
So no, it's not as simple as "She was created by male creators to be a fanservice character", because there's an element of truth to that, but the story is also a whole lot more complex.
Of course, since then she's been treated a lot less thoughtfully by subsequent writers and artists, but in her original incarnation, she was in no way objectified or treated as nothing but fanservice for male readers.
As for her body proportions - that's very Depending On the Artist, and it's true of pretty much all superheroines. Personally, I don't mind her being curvy as long as she has body proportions that a woman could actually have. I wish she'd be drawn more muscular, though.
look, i completely understand the whole being comfortable enough to walk around nude but honestly her coostumes she wears are ridiculous have you seen her most recent costume? that is some weird ass shit, and i would rather walk around naked then wear that skimpy bikini also, she can be as curvy as she wants, but her body proportions along with most other female heroes, are impossible also, because she is an alien, she would not have to ideal body , which is extremely unrealistic she is a fantasy character designed for her looks
Oh, you'll get no arguments from me that her most recent costume is ridiculous. Even her original costume was a bit too wardrobe-malfunction-prone for my taste. Frankly, I don't care how scantily-clad she wants to be, but the majority of her costumes haven't been even slightly practical.
And you have to understand, as a general rule I don't like superheroines wearing skimpy costumes for no apparent reason, either. Starfire is one of my few exceptions to that rule, because it really is quite character-driven in her case. I guess you could make the argument that none of them should have skimpy costumes at all, but if there was ever a character it actually made sense for, it's Starfire.
And certainly, as an alien it doesn't make much sense that she would look so much like a conventionally attractive human woman, but then again Superman looks /exactly/ like a conventionally attractive human man. It's unrealistic, but it's also really common to the genre.
