I don't think the tie fits with the rest, as gorgeous as it is. Everything else feels so... autumnal... that shantung doesn't really makes sense to me here.
The square looks really nice btw
Hm. Thats interesting - the jacket is linen/silk, quite textural. The square, a twill, gum silk-esque madderish texture. I thought a regular twill tie would have been out of place. I chose the shantung specifically for its nature to be worn with linen and summer things, as well as a texture to compliment the rest of the clothing.
But the jacket's color palette is autumnal, despite the yarn composition, and you're wearing (what looks like) flannel pants. I think a grenadine would have been better if you're looking for more texture - I don't know, shantung just says summer to me but it may be a personal bias. I would have picked a fall colored silk or wool/cashmere tie myself with this outfit. The shirt also looks great.
