Personally, because of the fact that I have lived amongst goyim and been raised amongst them, until my infamous return of my Neshama to Torah,,,,,,(just my 2 cents but…)
I think its a Chillul Hashem how nice we dress and carry on with conducting our lives with so much Gashmius. Lets face it we may have Olam Ha Ba but we have a lot LOT of Olam Ha Ze.
I know for a fact that they are not happy for us, when they see a woman dressed super sophisticated, pushing an expensive baby in an expensive outfit in an expensive carriage. Wearing a $5,000 ring.
Just my opinion, but I know that they believe our G-d would not want us to flaunt it, even if we have it, becuase that is the opposite of modesty.
And they resent that.
