Samus, adorned with her body armor, illustrates that beauty does not have to come from frivolous adornment and fine jewelry.  Her inner character of bravery and other such traits is what should be commended. 

"Your beauty should not come from outward adornment, such as elaborate hairstyles and the wearing of gold jewelry or fine clothes. Rather, it should be that of your inner self, the unfading beauty of a gentle and quiet spirit, which is of great worth in God’s sight." I Peter 3:3-4
