Sometimes I see comments about how nobody ever wears shawls nowadays and how they're not only not useful, but also not decorative, because they look like granny clothes. I think that's because people forgot. They don't know how to wear them anymore. For all the fineness and light weight, shawls can be surprisingly warm, so they're a good substitute for a jacket on cool nights, or for layering when you're going to some place where the air conditioning will be strong. And they're easy to remove and put in a bag when they're not needed anymore, unlike jackets.
This is the most simple way to wear a shawl. Just throw it over your shoulders, and you're good to go. Except after a while it starts to slide off, and you get annoyed and tired of keeping adjusting it all the time. One solution is to just tie it on the front, but I don't really like that. I like tieing it on the back:
I prefer to do it with circular and semi-circular shawls, but triangles work too. I think it looks great with a strapless dress or top, and besides warming up the shoulders and back (and arms, depending on the size), it's a way of showing less skin. For weddings, for example. Chic and modest for the church, easily removable for the party.
Same idea, different setting, great for low-cut tops:
Put the center over one shoulder, cross the points over the other shoulder, and fix it in place with a shawl pin or a brooch.
Or you could just roll it a little and wear it as a scarf.
I really like this option, but it's not equatorial zone friendly.
All pics were taken with the Aeolian shawl I just finished, so the effect might vary with different shapes or sizes, and of course there are lots of other possibilities that I didn't cover, or even thought about.
