Nobody else noticed it? Okay then. I guess I'll be the one to mention it. You forgot, like, half of your clothes.
Well you do know that the outfit isn't showing anything, correct? I mean, how is the outfit that is featured here different than a outfit someone would tend work out in? Well, it's not. It's a sports bra & shorts... Something we felt we'd see Rainbow Dash wearing, ya know, 'cause she's sporty and fast... She obviously wouldn't want tons of clothes on her weighing herself down and making her hot, right? All the Rainbow Dash cosplays we've seen feature a gaudy amount of tasteless clothes tied in with pointless rainbow accessories that makes it look like the person jumped in a bucket of tacky, useless, garbage that happens to be covered in rainbows. We definitely didn't want our cosplay to look like that. Here's something else to think, if someone had posted a picture of themselves in a bikini swimsuit, would it cause trouble? Doubt it. And hell, that's more revealing than this to be fair.
It's the same kind of clothes people go running and jogging in.... which ya know... yeah Rainbow Dash is kind of active. And by kind of, I mean extremely. It works. No different than something you'd see a woman jogging on the sidewalk in during summer. You said it perfectly.
Anyway... It's a nice-looking cosplay. I can totally picture RD wearing a necklace with her own face on it.
I had the necklace on previously considering I wear it around as an everyday thing. It wasn't intended to be apart of the costume though. Regardless, I'm sure she's self absorbed enough to wear herself on apparel.
