Wow, just wow! Look at that *Screams like fangirl* Oh good, simply wonderful! Your work is amazing ~! Just look at their expressions! c: I love how AJ is so nervous! :3 And Rarity...well she's excited for some reason ♥ I don't have any words to describe how beautiful is this! .w.
I personally disagree, but then again, I'm a fan of TwiDash too.
But seriously, there's actually more common ground here than there first appears. And they both share a very strong passion for what they do, even if they're very different. And, of course, AJ does actually know how to be fancy, she just chooses not to. Sisterhooves Social proved that Rarity is willing to get her hooves dirty (literally) for somepony she cares about.
