What could be more awesome than having a wider selection of ready-to-wear Marvel superhero costumes? Well, like Comics Alliance's Nick Nadel writes, it'd be a lot more awesome if these costumes actually looked much like the characters they're supposed to portray.
For example, there are three characters in the Marvel universe who might be considered female equivalents of Spider-Man: first, there's Spider-Woman**, who looks like this:
There's also Spider-Girl, who was introduced in a "What If?" one-shot comic, as the superpowered daughter of Spider-Man and his true love Mary Jane Watson. She dresses more or less exactly like her father does, in the blue-and-red spider suit:
Finally, there's Araña (Spanish for "spider"). She's a teenage girl with spider powers, and she dresses in street clothes with a spider motif:
None of these amazing characters look even a little bit like this, however.
This is more or less the pattern for all the characters featured in this line: make a standard-issue Sexy (Whatever) costume, with short skirt, bustier/crop top, and tall, vertiginously high-heeled boots, and add little details to evoke the character. Thus, Spider-Girl here looks more or less like the Black Cat looks more or less like Emma Frost looks more or less like American Dream. Only in Emma Frost's case is the resulting costume anywhere near resembling something the character in question would actually wear: hers is, if anything, a bit more modest than the outfit she wore for all those years as the White Queen of the Hellfire Club!
It does not compute, because Venom looks like this:You try to make that cute and attractive, and I'd argue you lost sight of the essence of the character a long time ago.
(In answer to your no-doubt-unasked question, "What's even more hilaristurbing than a Sexy Venom costume?", I give you a commenter at Comics Alliance's assertion that the blonde young woman modeling the Sexy Venom costume is none other than Carrie Prejean, Miss Anti-Gay California herself. How weird is that?)
**There have been multiple Spider-Women over the course of Marvel canon, but I am referring to Jessica Drew, the first, current and --- I believe --- longest-running holder of the title.
