It's time to buy or make some new clothes.
I'm going to go off of the 7th century description of naughty nuns who dress too well, as given in three translations by Gale Crocker-Owen in "Dress in Anglo-Saxon England." Fine linen undertunic, red or blue overtunic, sleeves striped with purple silk, bright or colored veil (showing hair around the face) held in place by a fillet.
I already have my Desborogh necklace-inspired necklace (A Met Museum repro, different mostly in being more symmetric and lacking the central cross) which is also 7th c. I may attempt a pouch like the Swallowcliffe Down burial one. The lyre still wants a fur-lined bag like the Sutton Hoo lyre had; I doubt I can swing beaver but sheep fleece is possible.
I'll try to do some amount of research into the appropriate shades of color. Amazingly, Wikipedia was actually concretely helpful in giving an example of Tyrian purple. (Whelk-dyed purple may be all right, especially if the silk was imported. I need to go to my books and see if we have any surviving colors. I know I've seen some lichen purples cited in Viking contexts.)
I go back and forth on whether or not the silk stripes ought to be decorated, and if so, how. Still under consideration.
