In Training Challenges, your look is scored according to the tags assigned to the challenge at hand. Every piece of clothing has two tags assigned to it, and matching the tags of your model’s clothes to the tags of the challenge, will earn you a higher score.  

Furthermore, you can boost your score with the Unworn and Trending bonuses. You can max your Unworn bonus by applying to a challenge wearing clothing you haven’t worn before. It’s possible to refresh the Unworn bonus on items you have already bought by clicking on the Reset Unworn button! You also can max your Trending bonus by wearing clothing with the Trending label over the thumbnail.
