If you use a long emote (it's more noticeable that way), and then change your skin, your character stands still without moving until the emote completes.

To see this for yourself, follow the steps;

1) Have at least 2 skins, one to use, and one to change to.

2) Use a long duration emote.

3) Quickly change your skin.

4) Go back to see your character standing there until the emote completes.
