My white latex top has gone yellowish, can I get the white back?

So my white latex top is looking distinctly cream now, almost yellow in a couple of places, and I am not thrilled about it. It has lived in a drawer, not out in any sunlight, so I am confused about what actually did this. Is this a stain I somehow caused, or is it just what light latex does as it ages? More to the point, can I get the white back, or do I make peace with a vintage look? I babied this thing, so I feel a little cheated. Has anyone here rescued a yellowed light piece?
