If you're not interested in feedback on what you're wearing, then probably is best that you quit here. Just because a jacket is sold without pants it doesn't make it an odd jacket. But, even if it did, it doesn't change the appeal of what you've combined here. I'll repeat my questions:
Does this really seem harmonious to you? Or even pleasingly discordant?
That´s the point: I have no problems with criticism. But only say: "Hey thats not a good look" or ask me question is not a real criticism.
Do you really think I choice that combo if I answered both questions with "No"?
So what makes the discordant for you? Which parts will you change for a more harmonious look?
The useful critique is that the jacket looks like an orphaned suit jacket and that such a look doesn't work. I didn't merely say that I didn't like it. As for the lack of harmony, the combination of the checked shirt with seersucker pants is jarring and unpleasant. I asked you because sometimes we put together things and, with the benefit of posting the picture, time, and some feedback, we can see things differently. Apparently you do not. Which is fine, but I doubt you will find many who will agree with your assessment of the combination.
For example, I have posted combinations about which I am unsure. Sometimes I become more convinced of the rightness, and other times I conclude I've missed the target.
