I assume that by 'ornaments' you mean jewellery or piercings.
Some Christian groups are very strict about jewellery but the vast majority of Christians have no rules about jewellery or piercings and are completely at ease with them.
In a christian church you can.
Yes pentecostal church members will not wear any gold ornaments to church

People attending a Pentecostal church can wear any clothing they choose. If you are female, wear what you feel happy with, be it a skirt, jeans or slacks. I've seen all types of clothing. All people have different tastes. The "Pentecostals" are believers in God like most Christian denominations and we don't have set rules on what clothing to wear, long as we look decent. If a church tells its followers what clothing to wear or not to wear, then get out of that church and find another one. God is interested in our heart not what we wear, provided that we dress decently. No church has the right to tell its followers what clothing to wear.
Well, if your inside a church then yes, but if your outside of church then you don't have to...it's your choice!
Anything, they don't mind. But wearing good clothes is a good idea.
Some people wear robes today in believer's baptism, but very commonly, and as in the early church, many people wear regular clothes. Preferably, clothes should be those that easily can get wet and be restored when dry.
There is no prohibition against wearing jewelry in Judaism.
There is no reason a Muslim bridesmaid cannot be at a Christian wedding. However, it is wise to check with the bridesmaid as to what she should wear in the wedding party if her family is still sticking to their old cultural ways.
Things like nose studs, lip rings, cheek embellishments and the like.
Anyone, Catholic or not, can wear the medal and pray to St. Jude.
they usually wore hair ornaments, tunics, and sandals.
