I like the concept of Rarity basically making RD fabulous and she’s peeved about it since it’s all girly BUT…
 
This outfit is a disaster. The corset is tacky and ill-fitting, why would Rarity ever put anyone in shorty shorts (or shorty shorts with a corset at all), fishnet stockings, with BLACK shoes (good lord, there’s not enough black in the corset to off-set those shoes), and that wig….looks really bad. I dunno if she originally had a good quality wig or if this is a halloween store wig but uh…it needs to go. Pretty much the only nice thing about this outfit is the layered rainbow ruffles she put in the back.
 
BUT as a said before, it’s a cute concept and I’m glad to see other mlp cosplayers doing things a little out of the box.

The horror….

Buck decorative corsets. Want to wear a corset, wear a proper one that makes you suffer the silent agony.

I think we both read into it a bit much. I may not like it but I’m sure others do. Either way it’s a nice attempt.

@RandomFanguy  
I think that’s part of the joke. Dash’s hair doesn’t look like usually does because of Rarity.
 
Ooooor I’m just reading way too much into this. :)

@ArrJaySketch  
Ah. Well, the thing is it doesn’t look very Rainbow Dash-y and it doesn’t look very Rarity-y. It just looks like a mess to me…
 
The corset needs something else to work right. Like a dress or elbow gloves.

@RandomFanguy  
I think it has to do with the fact that she’s wearing a corset. Rarity had Twilight wear a corset or girdle in the very first episode. :)

I don’t really get what this is supposed to be.
