Greek people...kosmios?

I was studying the Strong's word 2887, kosmios.

This word appears only in two passages, both in Timothy.

1Ti 2:9 In like manner also, that women adorn themselves in modest <2887> apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array;

1Ti 3:2 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour <2887>, given to hospitality, apt to teach;

The word kosmios is an adjective, derived from the word kosmos, meaning world or universe.

2887 kosmiov kosmios kos’-mee-os

from 2889 (in its primary sense); TDNT-3:895,459; adj

AV-modest 1, of good behaviour 1; 2

1) well arranged, seemly, modest

Kosmos means the following:

2889 kosmov kosmos kos’-mos

probably from the base of 2865; TDNT-3:868,459; n m

AV-world 186, adorning 1; 187

1) an apt and harmonious arrangement or constitution, order, government
2) ornament, decoration, adornment, i.e. the arrangement of the stars, ‘the heavenly hosts’, as the ornament of the heavens. #1Pe 3:3
3) the world, the universe
4) the circle of the earth, the earth
5) the inhabitants of the earth, men, the human family
6) the ungodly multitude; the whole mass of men alienated from God, and therefore hostile to the cause of Christ
7) world affairs, the aggregate of things earthly
7a) the whole circle of earthly goods, endowments riches, advantages, pleasures, etc, which although hollow and frail and fleeting, stir desire, seduce from God and are obstacles to the cause of Christ
8) any aggregate or general collection of particulars of any sort
8a) the Gentiles as contrasted to the Jews (#Ro 11:12 etc)
8b) of believers only, #John 1:29; 3:16; 3:17; 6:33; 12:47 #1Co 4:9; 2Co 5:19

I'm trying to figure out how we have translated kosmios to mean "modest" or "good behavior", when the root word is kosmos.

Can anyone help me here?

 

kosmos

11 Peter 3: ¶ Likewise, ye wives, be in subjection to your own husbands; that, if any obey not the word, they also may without the word be won by the conversation of the wives;
2 While they behold your chaste conversation coupled with fear.
3 Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel;
4 But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price.

The first word for adorning in verse 3 is kosmos. If anyone has studied the Greek, can anyone explain why kosmos, which is translated as world in most every other passage, is rendered adorning in this verse of Peter?

Thank you!
