'Outward Appearance' in the Bible

We are not commending ourselves to you again, but giving you an opportunity to be proud of us, so that you may have a reply for those who take pride in the outward appearance rather than in the heart.

So from this moment on, I do not estimate anybody by the standard of outward appearances. Although I once did estimate Christ by this standard, I do not do so any longer.

Do ye look on things after the outward appearance? If any man trust to himself that he is Christ's, let him of himself think this again, that, as he is Christ's, even so are we Christ's.
