Calculate New Portfolio Weights Given Today's Returns

I'm looking for a formula to recalculate my portfolio's weights at the end of time $$T$$ given a vector of the asset weights at $$T$$, and a vector of returns at $$T$$

For example:

weights = 0.2, 0.3, 0.5

returns = 0.05, -0.05, 0.10

How could I calculate what my new weighting going into $$T_{t+1}$$ would now be based on this information?
