Questions about in-game skins on online MM

I have a few questions about in-game skins on online Multiplayer/War Games (whatever you wanna call it). If you have a weapon skin equipped, will this weapon skin show up on your “stance”? During the match, will people see you with the weapon skin? If you die and drop your weapon, will the weapon skin still be on? If someone else picks up your weapon that you have dropped, will he/she have a weapon with a skin?

Probably, but obviously they wouldn’t keep it forever.
