These are three things rolled into one:
- A CASP edit that makes the boy-only Maxis longsleeves available for girls too
- 40 recolours of said longsleeve which are unisex
- Texture overrides for four of the existing variants ‒ no dramatic change, just a little added contrast and desaturation
All of the recolours are solid colours; most of them combinations of bright and less bright colours so one should always find something to match. They are available in Tops > T-Shirts right next to the original item; I’ve split them up into two thumbnails since 40 variants in one will mess with the CAS UI.
