bettycrocker, in this context, I think Una is referring to the texture of the fabric, not colours.
I agree with texstyle, Una -- a silk woven or a silk/ cotton blend, or a cotton gauze, or a rayon (though that will need ironing) -- all of those feel "soft" as opposed to "crisp" to me. I wear soft wovens very happily by the way -- though often in "crisp" colours. (i.e. blue and white).
I find it interesting that some of the reason people didn't like the butt vest for me was that I (in myself) was perceived as "too soft" to wear it successfully. It's all quite fascinating. My colouring (to bettycrocker's point) is cool or soft "summer." Which would theoretically mean that outfit 1 in my other thread (the blue and grey soft almost monochrome) should be perfection for me. But it's not. It's just barely okay, and lacks the animation I require, I think.
Hmm. Okay. I just made this all about me. Is it not all about me? Sorry!
Back to wovens...I would say the Lanai (if in wool) is somewhere in between. The wool drapes, etc. so that makes it soft, but it is a jacket, after all, so structured, which makes it somewhat crisp. On a continuum between a cardigan and an old fashioned corporate blazer, it would fall slightly to the right of middle. Cardigan being the left.
