    This study aims to formulate and evaluate of young Coconut Husk and Mayana Leaves dyestuff on silk fabric. Specifically, the study aim to achieve the following: to develop dyestuff using the different formulation of 60% Young Coconut Husk dyestuff and 40% Mayana Leaves dyestuff, to determine the color produced from 60% Young Coconut Husk dyestuff and 40% Mayana Leaves dyestuff in mordant used, to evaluate the colorfastness properties of the dyed silk fabric in terms of laundering, perspiration, and sunlight, and to determine whether there is a significant differences of the dyed silk fabric in terms of colorfastness to sunlight in mordant used. The study used the developmental- descriptive- evaluative research design. The statistical tool used was the weighted mean. For the colorfastness to perspiration and washing, the AATCC Test method was used. The color produced from 60 % coconut husk and 40 % mayana leaves produced are mocha using alum as mordant and khaki for copper sulphate. The dyed silk fabric with 60% coconut husk and 40% mayana leaves dyestuff and copper sulphate as fixing agent was resulted to very good performance in terms of colorfastness to laundering, perspiration and sunlight. Lastly, there was significant difference exists from the fastness to sunlight of the developed dyestuff using mordant use
