Sit bones and saddle width

Hi all,

I’m going through a phase where every saddle seems to give me discomfort. It feels like I’m sitting right on my sit bones even though I have both new and good quality bib shorts, and I keep getting saddle sores where my buttocks meet my thighs.

I went to local bike shop and sat on one of those sit bone width things. They recommended a narrow saddle so I bought a Power expert mirror saddle in a 130mm. This doesn’t seem to be helping things at all.

In recent times have also tried a bontrager Aeolus and a Merida expert saddle

I do wonder studying the picture more closely if I should be on a wider ~140-145mm saddle?
