I used to not like bright colors. I was into white/black/gray/grren/navy blue. When I was in college & started losing weight, my self-confidence skyrocketed, & I became more bold, & therefore my clothing style morphed.
I wore more "fitted" clothes (I used to wear baggy clothes), & I will wear almost any color. I wear pink&purple, as well as brighter "warm-weather" colors. :)
