i can see this being worn in k-8th. maybe not the heels. but it doesn't seem to match any other area.
it is the interpreter's job to be unobtrusive in their choice of clothing, and we may not always know if the clients we work with have visual issues with patterns or specific colors. it seems safer to wear contrasting colors that are neutral in design for the benefit of all clients we may work with, regardless of the location.
as a designated interpreter in an office setting
too "busy". should be solid.
d/b with a completely blind person, however many d/b have some sight/shadowing or usher's syndrome and will have residual. it may still be distracting. definitely not the accompanying accessories: necklace/rings - can be scratchy/catch on terp/db hands. it would be most wise to avoid.
remove the pattern and it would work.
without the pattern on the sweater
the pants are fine for k-12, or possibly community, but the sweater is very busy. it could still be professional, though.
too much pattern, in my humble opinion.
if the shirt were solid, it would be fine for post-secondary (college) interpreting.
