'90s Halloween Costumes: TLC What to wear for Tionne "T-Boz" Watkins: A bright, baggy shirt with even brighter pants. Add a short wig; two bang strands hanging down is a must. What to wear for Rozonda "Chilli" Thomas: The brightest, baggiest clothes you can find. Long, curly black hair is a must. What to wear for Lisa "Left Eye" Lopes: Again, bright baggy clothes, suspenders, and a backward cap. A patch or black mark under your eye is a must. How to act: Like the dopest girl group of the decade; harmonize "Waterfalls" and "Creep" as you see fit. Image Source: Everett Collection
