Red lace

[Wjames]

I know there's a lot of work to be done, but I hope it's improving, I'm having trouble with how to wrap up an ending...

A tiara shatters on concrete, I think this line might be a little stronger if it began with "my" instead of "a", but that's just persona preference.
Finally I see past Mercedes mask.
Fine merlot, expensive cologne drown me seems to me like there should be some sort of punctuation at the end of this line.
I saw the red lipstick on white collar too late. I don't know if you need "red", most people probably picture lipstick as red without it.
I gave you my pearls, you broke the string
all I had left in this world I think there should be a period here.
Red lace peeks from under your bed,
Multiple handprints splatter your door. I think multiple is redundant, as the "s" at the end of handprint implies there's more than one.

I think you could improve the title; I generally try and stay away from having the title appear in the poem itself. A strong title can add another layer to the meaning of the poem.
