(( Disclaimer: I roleplay as Rarity, and I'm going to let her say what she wants about this piece. ))
On the left, I'm assuming that she's simply using the measuring tape as a prop, and not actually measuring the dress, as it looks to be finished, even including a belt on the mannequin. I appreciate the color scheme for the outfit, having it in purple, white, and just a hint of black. I also like the fact that a corset is implied but not actually used in the outfit, as it's a clever reference to how fashion changes at a moment's notice. Now for the right. I'm reminded of "Suited for Success" when Rarity was talking to the camera and made the duckface ( for reference ) near the beginning of the episode. However, I have to agree that the Cutie Mark is slightly misplaced, as it should be about 4 and a half inches higher on the buttock, as that would correspond more closely with where it is on the actual pony.
Overall, I have to say that this was quite well done.
(( I have to agree with Rarity here; after all, my personality is a lot like her, even when I'm NOT roleplaying. I suppose that's why I chose her to roleplay as. ))
Hmmm...The cutie mark is a little too far back should be just at the pelvic bones midpoint. And then hair should have a sleeker complexion. More of a deep purple as well. The hair is also a bit long. It should drop somewhere a little farther after the shoulder. Maybe.
You have a lovely figure. Very trimmed and petite a true Rarity of rarity's if i've ever seen one. I love the horn as well. Excellent shape. And although I am not entirely sure how paleness settles with most. When cos playing rarity the paler the better. Maybe a little make up.
How is it pointless? If someone happens to like Rarity and they're not exactly a furry, they'll enjoy this. That simple.
If something exists, there's going to be lewd material made of it. ESPECIALLY if it has a fandom as large as MLP. She's naked. That's it. This is extremely tame and tasteful compared to most of material the MLP fandom has produced.
I'm sorry for having an opinion about this? Such butthurt man, chill out. I like the actual outfit she made, I do not like that she had to get naked as well. That's all there is to how I feel about this.
