Why do some women hate it when another woman is wearing the same dress?

Clothes reflect your personality and if everybody wears the same, you blend into the background more. If you notice somebody else wearing the same, your individuality becomes compromised.

Clothes have the power to make you feel unique and invincible.
If somebody else is wearing the same, human nature is to contrast and compare and that brings out your insecurities if you no longer feel 'invincible'.

Never bothered me I would actually be the one to point it out. Other girls didn't seem to like it tho especially when I pointed it out.

They want to feel unique

I’d probably laugh 😆 and say what great taste she had

With the infinite selection of styles out there, The chance if spotting someone wearing the same dress or top as you are pretty slim.

The ONE tie I have had it happen, I marveled at the coincidence of it all.

To go to all those rounds
The hair, the make up, the shoes, and someone else looking the same steals tunder

I never knew.

Because you look better in it lol
