But I guess the vendors will make what they think will sell best.

 

It's not only that ... but a clothing set that is more detailed, and involves more pieces that work together (such as a jacket over a shirt, or a shirt that tucks inside pants, etc etc etc) take longer to make. They have to be fit so that they adjust together properly, body morphs have to be developed and checked, there are style and movement morphs involved, the weight mapping on each piece needs to be checked and tweaked, and so on.

Ana has only been released for a short time, but there are things being worked on. Just be patient. 8-)
