What is the meaning of the poem "Black Silk" by Tess Gallagher?

Hi. Some says it was about a woman who was grieving the lost of a love one, by the poem we can see that it was a man, because of a man black silk-vest. She found it while she was cleaning and folding clothes up in her bed room, as she put the vest on, pain of yesterday overcame and over power her, i guest she was talking to a female friend, the poem does not tell us if the female, was her daughter, a friend, or some one she was baby siting at the time, but we know, that she was talking to a female person. is a rare poem of loss, faith, and returns—return to the site of loving and to the gradual last breath, return to life's immediate summonings. Yet, despite the obvious difficulty of undertaking such painful personal material, (The vest) she could always moved on because he was still alive in her presence, in her mind and in her heart and spirit. The elegiac danger of self-indulgence is routed here by a poetic spirit that is genuine, generous, good-humored, is filled with wonder—the kind of wonder the title poem alludes to as it rejects aesthetics or faith in favor of something ineffable. Each dream, each speculation, springs from the desire of the living to know what only the dead can know. With refreshing honesty, Gallagher walks right up to the walls she cannot scale and comes close enough to feel their texture...Whatever such material may ultimately mean to her private life, it has left her a more powerful, confident, and convincing poet."
