This is a Maxis Recolour which means that it is a recolour of an item that already exists in your game. Please check the Expansion pack requirements to see which game pack it recolours.
These are texture replacements for afbodyshirtuntuckedoxford, the base game's AF untucked longsleeve shirt with capris. Both sets use the shoes from this default by Aquilegia and the pants from this default by silivrin. If I'm reading their credits right, the pants are by Trapping, and the shoes are from an unidentified Maxis outfit. In addition, I have uploaded a non-default version of each default set. Each set is in its own rar file. Textures in the default packages are Compressorized, resources in the custom packages are compressed with SimPE.
Remember, you can only use one default for afbodyshirtuntuckedoxford at any given time, so if you want to use both of these sets, at least one has to be a non-default version.
The shirts in set 1) are from silivrin's default, and are basically the unedited Maxis shirts, though I think one or two have color tweaks. The shirts in set 2), except for the yellow one, are from Aquilegia's default, and are Maxis textures edited and recolored by Aquilegia. Since Aquilegia didn't replace the incomplete afbodyshirtuntuckedoxford outfit, I made the yellow recolor to complete the set. Set 3) is a non-default version of 1), and set 4) is a non-default version of 2). The rar and package files are tagged with either "MaxisShirts" or "AquilShirts", so you can tell which shirts they use. In the image, the outfit on the left side of each pair is from set 1), while the one on the right side is from set 2). Click the button to see the image.
The outfits with the white/ivory shirts replace one (afbodyshirtuntuckedoxford-ivory) that Maxis left incomplete, so they will not appear unless a completer mod or a custom version is used. The completer will make afbodyshirtuntuckedoxford-ivory available to both YAF and AF, but whether the other replacement outfits will be available to YAF depends on what, besides University, is installed. If they are not available for YAF, an optional category mod to YA-enable them is in a separate rar file. See Place in Program Files under the Install Instructions tab for instructions on installing this mod. The custom versions are available as Everyday to both adults and young adults.
Maxis, for the mesh and original textures.
Trapping, for the pants retexture. Aquilegia and silivrin for the replacement textures I blended to make these outfits.
