This is Lightbrite (real name Shimooka Hikari) from Ogino Jun's manga γ-gamma-
Just one among the many superheroes/supervillains in that series.

I find it weird yet visually pleasing that she spends most of her time with covered nipples and a cameltoe. But it turns out that the reason behind that is in her suit's actual functional design explained in the recent chapter (chapter 12 as of this post).

Still love her though.
