Select “Programs and Features”.

Tap on the box that says “Can’t decide what to wear? Outfit Compare”.

Tap on “Get Started”.

Tap on “Add First Outfit”.

Select either “Take a photo” or “Photo library” (if you already took the photos).

Take the photo or select it from your camera roll and add it. It will appear in the app to the left. Then tap on “Add Second Outfit”.

Once you’ve added the second photo, tap on “Compare Now”.

The two photos will be submitted and the process should take about a minute or less. You’ll get a notification when the results are in.

Unfortunately, you can only compare two outfits at once. So if you have more than that, it might be best to compare two of them, and then compare the winner to another outfit that you’re deciding on.
