I wasn't originally planning on making this during Pride Month but I saw some binders for Sims 2 and then remembered someone had done this for Sims 4, so I... kind of recreated it for Sims 2. It's simply a recolor of these breathable binders by Simstrailia with this Miku pattern over the dark blue swatch.

TU-EU, comes in Androgyny shapes for all and EA bodyshapes for male. Categorized the same as the original (so everyday/swimwear/undies/gym), so you'll need this mod to get the separates to show up for other categories. The preview shows the androgyny teen, androgyny adult female, and EA adult male. All meshes are included.

(Yes, you aren't supposed to wear binders while exercising but maybe Sim physiology is a bit more robust. I still haven't had a sim die of illness after all).
