If you have foreach include, read the section about custom iterators. Otherwise:

pawn Код:

stock RemoveClothes(playerid,slotid)
{
    ClothesItems[playerid][slotid] = 0;
    for(new i = slotid + 1; i != HasClothes[playerid]; ++i) {
        ClothesItems[playerid][i - 1] = ClothesItems[playerid][i];
    }
    HasClothes[playerid]--;
    return 1;
}

1. Remove item
2. Move all items to -1 slot
3. Decrease number of clothes

Remember to update HasClothes on addition/removal of clothes.

There is also fancy way using pointer swapping (introduced by Slice https://sampforum.blast.hk/showthread.php?tid=343172 ), but I think it won't be necessary.
