For Duelist PvP Roblox , skins are usually equipped from the skins/customization menu in the lobby , not from your normal inventory. A recent TikTok tutorial also notes that you may need to click the Change button twice for it to stick.

How to equip them

  1. Open the game and go to the lobby/menu area.
  2. Find the Skins section or a similar customization icon.
  3. Select the weapon/item skin you want.
  4. Press Change/Equip.
  5. If it does not save, click Change again.

If it does not work

  • Make sure you actually own the skin.
  • Some Roblox games only let you equip a skin if you also own the base item it belongs to, which is a common skin-system rule shown in similar Roblox guides.
  • If you are on mobile, the button placement may be a little different, but the same idea applies: open skins, pick one, then confirm.

Quick note

I did not find an official Duelist PvP guide in the results, so the safest answer is the menu path above based on recent player tutorials and Roblox skin-menu behavior.

TL;DR: Go to the Skins menu in the lobby, choose the skin, hit Change/Equip , and tap Change again if it does not apply.
