How do I tell my girlfriend her eyebrows look awful?

We are both females, I’m 29 and she’s 25. She previously didn’t do anything with her eyebrows. Recently she shaved the beginning of her eyebrows. If you know brow anatomy they should start about in line with the outer edges of your nostrils. She shaved them to where they start in line with her pupils. It looks awful, they’re so far apart. When she came out of the bathroom I gasped and asked what happened with her eyebrows. She said “nothing! I always do them like this” and I pointed out that they were much wider than normal. She denied that and again said that nothing was different. I had recent pictures of her to prove that this was not how she normally did her eyebrows, but I didn’t want to embarrass her so I didn’t say anything else.

I thought maybe she just messed up and didn’t want to say anything, so I waited. It’s been weeks and she is continuing to shave them super wide. She mentioned about a week ago that she wanted to go somewhere to get her eyebrows done. I recommended the girl I go to, who is excellent and fully maps out your brows every time. I sent her all the info then she never scheduled anything. How do I tell her without insulting her?
