The dancer is a woman with a black shiny leather dress, with a garterbelt that connects it to her shiny black boots. The back of the dress has a large countess collar. She also wears a beautiful flowing golden evening gown, with the hems of the sleeves and the skirt flowing freely. A hot pink dress hoop "pushes" the gown out, making it look more like a 16th-century ballroom dress. She has a gold choker scarf, and has blondish puffy hair that is curled at the end. She wears a hot pink glove, and a black visor on her face.
The dancer transforms into a completely different outfit. She wears a shiny brown long sleeve crop-top that exposes the midriff, and black cuffs at the end. She also wears a black collar. As for the shorts, they are shiny and brown too, with black cuffs on the hips as well. She wears burgundy ankle length high heel boots, and a similar looking brown glove. Her hair does not appear curled at the ends anymore, and the blonde hair is slightly more pale. She wears a black butterfly-shaped visor on her face.
The coach wears an outfit inspired by the official music video.
A bodysuit with flowing cuffs over the hands.
The suit is possibly made out of sheer fabric, as black spandex shorts and a black strapless bra are visible underneath.
She wears a black hair cap over her hair.
White face paint, with smudged blue eye-shadow and orange smudged lipstick, like Lady Gaga in the music video.
She also wears black ankle-length boots.
There is also a noticeable, fiery, static-like outline around the dancer as well.
The routine takes place in what appears to be an insane asylum. During the first verses of the song, she appears in a long slender hall with screens with people trying to get out on the sides. Lights light up the floor, and make various triangular formations as she dances. The people in the screens on the sides try to push out, but cannot, due to the unknown material. As the chorus nears, back-up dancers appear: two men wearing only pink spandex pants and with a strange hairstyle, and two women wearing a pink one-piece, with long brown hair. They dance during the chorus too, and also during the chorus, the wall itself is another giant screen in which once again a person is trying to get out.
The routine takes place upon the same stage as the On-Stage routines, with various lights and an audience.
There are 3 Gold Moves in the Classic routine: All Gold Moves: Bring your right hand down in a curve while hopping and put your left arm down.
All Gold Moves
All Gold Moves in-game
There are 3 Gold Moves in the Alternate routine: Gold Moves 1 and 3: Spread your arms out from your chest such that they are outstretched. Gold Move 2: Raise your arms with a slight bend, as if you are flexing. Also, keep the rest of your body entirely straight.
Both modes of Applause appears in Party Master Modes; here are the captions attributed to their dance moves:
Black Swan 
This is the second song by Lady Gaga in the series, after Just Dance.
The Alternate routine uses the On-Stage Mode's background, despite not having its lyrics in the middle of the screen and the dancer being solo.
The back-up dancers in the background are the first dancers in the series to have visible skin tone, and faces, as opposed to the neon style of the main coaches.
The dancer for this song has the most "3-D" effect added to the skin of the dancer.
The two dancers do not have a "smooth" transition in between each other and is one of the few to do so.
Safe And Sound just has a flash when the dancers change, and Wild has sort of a glitchy transition.
The pictogram for the last move has the same colour as the ones for the verses, meaning that the coach was probably meant to appear in her initial look instead of the chorus one, or maybe they just recycled the pictogram to not waste time recolouring it, as it happens in every game the song is featured in.
If you bought Just Dance 2014 from GameStop and bought the ARTPOP album (follow instructions on receipt), you would have gotten an additional remix of Applause, the Bent Collective Club Mix.
The Alternative version is noticeably harder than Ubisoft's usual choreography, since it is the original choreography of Richy Jackson. This could possibly be the hardest choreography in the game, even surpassing the difficulty of some, if not all, the Extreme versions of songs in Just Dance 2014. However, it is only marked as "Hard."
A very short video of the Alternate routine was leaked on November 21, 2013.
The alternative dancer spells "ARTPOP" out with her hands at the end of the song just like Lady Gaga in the music video; however, some people may find this difficult, and because of this, it isn't counted as a move in-game.
In the Just Dance Wii U trailer the title was accidentally spelled as The Applause. This was fixed before the final release.
If you look closely to the Alternate coach, you will see her lip syncing throughout the lyrics.
This is normal, considering that she is dancing in the On-Stage Mode background.
