If someone new befriended you and immediately started dressing exactly like you, would that be jealousy 🤔 or flattery?

This is happening to me with my new caregiver who is 20 years younger than me - but of course I do dress pretty cool still. 😎
I don't want her to copy me. We used to do that kind of thing during our school days and it was okay πŸ‘ back then.
It's creeping me out. She said when I first met her that she usually wears black leggings and a tight fitting T-shirt which is not very becoming on her because her tight T-shirts show her rolls of fat. I told her I have never bought or wore leggings and that I wear dresses πŸ‘— more than anything. Now she's wearing dresses just like the one's that I wear.πŸ™„
