I like this a lot, mainly because it does an excellent "shoulder season" job. It's slowly moving towards autumn, but it's still quite hot & sunny and way too early to think about heavier materials. The colours in this outfit neatly hint at the season to come but are all in light, temperature-appropriate materials. Very well done.

Thanks, HF. I find autumn to be one of the more difficult seasons when it comes to dressing. You want to dress in more wintery colours, but it's often too warm for heavy wools, flannels and tweeds, especially when the temperature is still over 20C. Wearing linen in more muted colours is a good solution for this problem, and I guess it can also be used in those awkward late winter/early spring months. Anyway, you can put it much more eloquently then I can.
Your orange tie is especially festive, and although this square goes very will with it, I can't help but feeling the tie is a little alone right now in your outfit. It could use a friend or two that hint at festiveness as well. Perhaps a less dark/businessy suit would've helped?
