Features:

Does not modify any NPC outfits.
Tailored tops for outfits with skirts to cut a curvy hourglass silhouette and reduce clipping with new skirts.
When wearing robes which are closed in front, skirts are replaced with short pants to reduce clipping.
Gladrags now has a custom plaid outfit with short skirt, available in various house colors.
Legs are reshaped to look good with short skirts, and character skin color is propagated to legs and feet.
Gladrags now has sheer hosiery available in various colors (black, white, suntan, and blue).
Hosiery is equipped in the "Handwear" section (the same way you equip gloves), so you can wear any hosiery with any outfit.
Gladrags now has various shoes and boots available.
Shoes are equipped in the "Facewear" section (the same way you equip glasses), so you can wear any shoes or boots with any outfit.
When wearing outfits with pants, selecting hosiery will affect the socks color and make them sheer.
Added the option to remove socks. Purchase this as an item in Gladrags and equip in "Handwear."
Added the option to remove shoes. Purchase this as an item in Gladrags and equip in "Facewear." You can re-equip socks after removing shoes.

Most likely incompatible with my previous sheer tights mod ( https://www.curseforge.com/hogwarts-legacy/mods/asheersilkytights ). Recommend un-installing/unstaging my previous mod when installing/staging this mod.
I designed the tights and calibrated the colors using skincolor#7. The mod will work with any skincolor, but for the darkest skincolors, the tights will look more opaque and the color will be slightly modified. Skin color can be changed mid-game using the "character editor" mod.
Equip custom hosiery purchased from Gladrags in the "Handwear" section the same way you equip gloves.
Equip shoes purchased from Gladrags in the "Facewear" section the same way you equip glasses.
Equipping shoes may sometimes remove socks. If that happens, just re-equip the socks in the "Handwear" section.
Compatible with the female reshape mod by deathlysallows, as long as this mod is installed after the female reshape mod (for example, mod#1 is femalereshapemod, and mod#2 is this mod).
Install the "Reduce Scarf and Necklace Clipping for Reshaped Tops" mod if you plan to wear scarves or necklaces when using this mod.
Recommend using the "Vendor Refresh" mod to refresh Gladrags stock if you don't see the hosiery and shoes in the shop.

The white and tan hosiery have a greenish tint in the pause menu due to a green spotlight in the pause menu which the modkit doesn't support modifying. The hosiery should look correct in the actual game.
Since hosiery is in the handwear section, you cannot currently equip hosiery and gloves at the same time.
Since shoes are in the facewear section, changing the shoes of an outfit means you cannot simultaneously equip glasses or masks.
Skirt physics is disabled when wearing robes to reduce clipping. Skirt physics is still enabled when wearing capes.
Some shoe options will clip with some pants options. Recommend picking shoes compatible with your pants. All shoe options should work with all custom skirts.
