Wouldn't it be great to unify broad reach of your social network and users’ ability to vote for your idea but also enable voters to make suggestions?
Advise Me app does just that - users posting outfits ideas/looks immediately receive fashion evaluation and advice from other users (be it friends or broader community).
Based on feedback one could decide, what clothing variants (dress/shoes/etc.) look better to wear or buy. The advantage over social messengers is that users could receive fast and quality ratings consolidating both negative and positive feedback as well as suggestions.
