If you found some really good-looking Looks created by a player and want to regularly check for some other Looks they submit or even compete with them, then you can Follow the player.
To do so, open any player's profile and click on the button highlighted in the picture below:
Once you follow a player, you can get instant access to their profile and check what looks they have recently posted, what Badges they have and who else they follow by clicking the "Followers" button while in your profile. There you can also see a list of players who follow you.
What are Friends?
If two players are following each other, they are Friends in Pocket Styler. This allows you to compete with each other in a dedicated Leaderboard for Friends. You can find this leaderboard by clicking on the Friends tab while checking the Leaders.
If you both follow each other but don't see your new friend in the list of the Leaderboard, you both need to earn some Crowns by receiving the scores for submitted looks to appear thereafter.
