Thank you all for your answers.
I'm not really sure about the leather moto... I mean, this outfit is a bit classic. I guess that's actually the point of adding the leather moto jacket.
I like the all grey look, however adding colour looks like a good idea. For example, what about a red leather jacket?
@rachylou, thanks for your sincerety. I think I understand what you say about the "puritan" look of the blouse. Anyway, I really love this charmeuse shirt style, and I think that it can always be combined in a fashionable way.
Maybe that's not the general appreciation. I really wonder what others think about the shirt. Perhaps I should open another thread for that
