I have asked your opinion if I should keep or purge my grey denim jacket here. Here is a second chapter.
I have decided to try to style this jacket once more and even browsed Pinterest for inspiration last night. I came away with a grey jacket over a column of white with silver accents.
So this is what I wore today - pic 1. While it was not a disaster but I did not feel overly fab either. By the end of the day (and in a big part thanks to your wise comments) I was leaning towards a purge...but decided to do a little experiment first.
Here I tried 4 other jackets I own with the same outfit and took pictures (pic 2-5) #3 is as casual as the grey one and ##2,4 and 5 are dressier options - but in each of them I felt much better than in the grey. Like by 1000% better!
It is no brainer now - this grey jacket is going...going...gone! It frees space for my new cream Zara jacket (pic 5) which I enjoy wearing much-much more!
I still think this experiment was very useful for me today. Now I have no regrets, no "what ifs", no looking back!
Thank you for all your help - just wanted to share with you my decision which you helped to make!
