These are really sad days, we all know them, unfortunately.
I've lost my beloved Mom suddenly last June(but after 1,5 year of hard time with her condition) and it was all a mare- but I was so grateful having a fuss free and trusted funeral outfit from 1 year earlier, when my FIL unfortunatley passed away.

Then, I was mourning her all summer and I simply wasn't able to wear my hapy patterns, the white jeans or my summer brights. It's true I love my all (textured) blacks (in winter) and contrasted (with bright whites) in summer but not head to toe and day after day- so I am really intrigued looking back- but black was all I needed last summer- and it really helped to hide my suffering.
I commiserate with you in your worst days.
