Thanks DB!! Wish it were so!
The frames are SALT. Really like them myself!
I would say that the material, cut and colour all play a part in conveying the "hardness" or "softness" of a particular outfit and the key is to balance them to achieve the effect that you want. The person's face and perhaps their body-type would also come into play here.
I would aim for neither extreme but perhaps a middle ground, i.e. a "soft" outfit balanced with elements of "hardness" or vice-versa.
As always, once you understand the elements that constitute this framework, it would be interesting to test the effect this has on the people you interact with.
