Unsure - Send Ring Sizer First

The sizer itself is thumbs up : )

But I saw some reviews seemed to have size issues, so I am writing a hat trick below

I was not sure my ring size, but I remembered about our body gets swollen throughout day due to diet, sleeping, etc.

Did 1) and 2) for two days

1) measure during morning and took a picture( where the arrow points at )

2) measure during evening and took a picture

3) look over all photos and pick the largest measurement

4) attach the picture to reply email seeking an advice (if not sure about)

Hope this helps
