And the winner is...
Aramek! Congratulations! You have won this round of the Rarity's Roughnecks contest! (PM me for your choice of prize and shipping address.)Aramek - The Breakfast at Tiffany's/Audrey Hepburn look is great! This is definitely the kind of thing Rarity as a character would go for; being the center of attention at high-class parties and whatnot. The grey looks good with the darker stockings/gloves in the night-ish background, and is a softer contrast than an entirely bold black. The sunglasses monocle sets a good focus piece on Rarity's head as well to complete the outfit. Excellently done.

synthorange - What a wild costume! It's like a beatnik hip-hop breakdancer look, and I'm surprised you put that together so quickly! A darker background would have been nicer, especially since the straps and red/black colors make it seem like it might belong closer to Halloween, but I can't stop smiling at her crazy poses.
OFSheep -

(No honestly I give props to this for crazy originality and a good use for NO MANE, but by gawd!)
Strabo - YOU GOT THE POWERRRRR! Very flamboyant, and I love the eye expressions you used. The cape was a bit much though, since it gives off a kind of Evil Knievel vibe.
CapacitorPlague - An urban cowboy! I like this black-and-blue denim look, but what's with the watch?
Highbrow Dash - Our first Sonic Rainboom reference!

The colors could stay a little more consistent, although it is a good try at the insane beauty pageant look Rarity wore in that episode.
Crow - Very bright and sunny! Good choice of a background to go with the yellow, but I think the big bow tie and monocle accessory kind of clashes with each other since the bow tie fits with the more innocent look and the monocle is for more formal things.
Milli - This is a good look, but my attention is drawn away to the only red piece in her ensemble, which stands out a bit. Perhaps maybe if another major part were also red, it may work, but it's a hard toss-up on which yellow piece should be sacrificed for it. Good use of face pose and striped hair though.
Mechanical Ape - So good! The red dress and accessories make Rarity look like Scarlett Johansson on the red carpet at the Golden Globe Awards! The only misgiving I have about this look are the black, strap-happy shoes. Otherwise, the episode reference nose pose coupled with the nightly background to go with my aforementioned Golden Globe scenario had me very conflicted between choosing yours and Aramek's when I had to whittle down the entries! Good job!
diribigal - Now yours is a good example of making simplicity in colors look good. Purple compliments Rarity all the way, and I like yours for being the only one to bring out Rarity's trademark horned glasses.
Kudos to everyone who participated! You all did a very good job!(Anyone can now post in this thread.)
