First appears in Intrigue at the Indy 500 and again in:

Father's Day. 

The Jem Model sheet number for this fashion is J-51, which is a bit confusing because that's also the model sheet number for Jem Star Pants J Shirt.  The episode numbers of the code correspond to their respective episodes, however.

The same pattern was used for all of the Holograms.  Only the colours and slight variations in jewellery and shoes set them apart from each other.

Culture Clash, Glitter And Gold and The Talent Search Part 2.

Hollywood Jem Part 1.

Kimber, Aja, and Shana each have recoloured versions of this fashion.

The Bands Break Up, Journey Through Time, Hollywood Jem Part 1, Hollywood Jem Part 2 (reused footage), Video Wars.

Kimber, Aja, Raya and Shana each have recoloured versions of this fashion.

The Fan, Father's Day, The Presidential Dilemma, Beauty and the Rock Promoter, Straight From the Heart.

The Jem Model sheet number for this fashion is J-59.  It was designed for this episode.  There is a special designation on the model sheet that states "Jem wears glitter and gold make-up with this outfit."

Scandal, Father's Day, Aztec Enchantment, The Presidential Dilemma, Britrock.

Differs from the produced version, in that the tights have silver dots and not the bodice of the dress.  She is also not shown with any hair ribbons or bracelets.  Her shoes are also purple, not hot pink.

The Talent Search Part 1, Trick or Techrat, Riot's Hope.

The Jem Model sheet number for this fashion is J-61.  This fashion was designed for this episode, it even has the scenes for it specifically noted.  It is also labelled "Flash and Sizzle," possibly for the make up scheme.

She wears white tights and gold pumps with this fashion in the cartoon, not turquoise tights and ankle boots like the dolls' produced fashion.

This is a reworked version of the original model cel, which can be viewed on Felicity-Chan's cel gallery.

The Talent Search Part 1, Trick or Techrat, Renaissance Woman, 

The Jem Model sheet number for this fashion is J-62.
This fashion was designed for this episode, it even has the scenes for it specifically noted.  It is also labelled "Flash and Sizzle," for the make up scheme.

The cartoon version shows her with pink pumps, not ankle boots.

This is a reworked version of the original model cel, which can be viewed on Felicity-Chan's cel gallery.

Being a video fashion, this outfit is likely only ever shown in this video, and was not designed by the main Jem designers.

Straight From the Heart, A Change of Heart*.

*Have been told but still have to personally check.

The Fan, Alone Again, 

The Fan, 

This version first appears in The Bands Break Up.

Variation: Looks quite different in the opening credits.
Variation: in pink/blue, shown on a poster in The Presidential Dilemma. 

Danse Time, Middle of Nowhere, 

Danse Time, Roxy Rumbles, 

First appears in Danse Time and again in:

Hollywood Jem Part 1, Video Wars.

Interestingly, the Jem Model sheet number for this fashion is J-54-25, meaning it was actually designed the first season (maybe for Culture Clash) but for whatever reason did not get used until this episode.
