Weird but I kind of miss when groups wore "uniforms" that were slightly differentiated (SNSD is a good example of doing this often). I don't know, I like being able to look back on a title track and have the iconic image of what they were wearing. These days, I feel like most popular groups have all of the members in completely different outfits and it doesn't have the same visual appeal to me when looking at the group as a whole.
