A.T. Robertson Commentary 1 Peter 3:5

"For after this manner aforetime the holy women also, who hoped in God, adorned themselves, being in subjection to their own husbands:" — 1 Peter 3:5 (ASV)

Adorned themselves (εκοσμουν εαυτας). Imperfect active of customary action, "used to adorn themselves." Κοσμεω is old verb from κοσμος in the sense in verse 3. See Heb 11:11,35 for like tribute to holy women of the O.T. The participle υποτασσομενα repeats verse 1.
