Disguise Oneself

You make a John Cena hand movement and speak the words, "You can't see me... as I am." Magic then transforms you and your armor, weapons and gear into whatever you choose. You can appear 1 foot taller or shorter, but must keep the general size of your exiting body. The disguise is an illusion and cannot stand up to physical inspection. 

For a creature to see through the illusion it must use an action to inspect your appearance and must meet or exceed your spell save DC on Intelligence (Investigation).

This is definitely not Disguise Self
