They never appear in the same outfit once they are split in two in De-Void.

When the Notisune and Stiles were in the same body he had access to all that Stiles had.

When they split, Nogitsune/Stiles appears in the same clothes he had before the split (seen in both De-Void and Insatiable) while the real Stiles first appears wearing the bandages and bomber jacket from Rhys.

In The Divine Move, Stiles changes into a plaid while the nogisune has a fresh grey shirt and adds a jean jacket.

It is unknown from whence the Nogitsune's articles of clothing came or if they are simply an illusion.
