While wearing the traditional attire, one must have the sacred thread (Yagnopavitam/Poonal) around one’s ear. After wearing the dress, one performs achamanam after washing hands and legs which is followed by adorning of Thiruman.
Thiruman must not be adorned while the sacred thread is around one’s ear. Because sacred thread can be worn only after washing hands and legs, immediately after wearing the attire, one must wash hands and legs, wear the sacred thread properly, perform achanaman, and only after these must adorn Thiruman.
