I have only done the Fit skins as in some cases I only had the fit mesh to work from.  If you have a thin or fat mesh that the skin would fit onto, then simply rename these bitmaps from "fit" to "fat" or "skn".
(ie. "b010faFitlgt_MaxisRockstar01" becomes "b010faSknlgt_MaxisRockstar01")

Sequinned MiniDresses
[From HP Costume Trunk (b200FaFit or b024FaFit)]
I couldn't quite work out which looked better, a b200 mesh (left) or the B024 Uber (right).  The skirt is a fraction too short on the b200, but there was something not quite right about the b024 either.  So you can choose which one you like better (b024 has larger breasts and a tight skirt).
[B200 Union Jack (All skin tones)]  [B200 Green/Gold (All skin tones)]
[B024 Union Jack (All skin tones)]  [B024 Green/Gold (All skin tones)]

These skins use the B200 or B024 default Meshes, the High Heeled B200 version is pictured above.
If you need the Jerome High Heels b200 mesh too, Grab it here

Old Fashioned Dress
[From HP Costume Trunk (b326FaFit or Bj82FaFit)]
In the Costume Trunk the dress is longer and less fitted (with a bustle?), so the closest mesh I found to fit it is the b326 mesh (On the right).  This means that the white lace trim on the skirt looks like white stockings and it has high heeled boots.  I think it also looks nice on the "Arwen" mesh (Bj82, Left), but the boots then become the hem of the dress (Which you won't notice in the game because it isn't as close up). So you can choose.

Swimwear
[From HP Costume Trunk (b300FaFit)]
[Floral Bikini] [Blue Bathers]  [Nautical Bathers]
Each zip contains all Skin tones. Fit only. All these skins use the b300 default Mesh.
If you want these as the default swimwear change the name to "UFFitLgt_01".  With "Drk" or "Med" substituted.  Skinny and Fat women look ok in Fit clothes too, so you can rename the "fit" to "Fat" or "Skn" too if you like.  Head not included in Zip.

Temple Priestesses
[From HP Costume Trunk (b325FaFit)]
The White dress is in House Party as an outfit in the Create a Sim screen, so I don't know why it was included in the Costume trunk also, but I have it here too, incase there is a difference I can't see
