To incorporate lights into your clothes, get some electronic scrap, a bolt of fabric, electro tech skill and a toolbelt. If crafted successfully, the bolt of fabric can support a %glowcolor which can be added to both the description and the teases, and allows the tailor to add in basic electronics like fiber optic strands and LEDs. Optionally, these pieces require both artistry and electro tech to finalize.
(If you wanna be really mean? If you crit fail the electro tech test, you get zapped and the bolt gets set on fire.)
