So what is the etiquette when you notice that an acquaintance has had some sort of cosmetic procedure? Maybe teeth straightened or whitened or hair implants or botox, or whatever you like. Do you mention it?
On the one hand, if they were vain enough to have it, maybe they will appreciate that you have noticed. OTOH, maybe they will be embarrassed.
You say “Hey, you are looking GREAT!” Don’t go into details about how the teeth are whiter or the hair is fuller. If they want to tell you, they’ll tell you. If not, they’ll be happy to think that you only noticed that they are improved, somehow.
My best friend told me that she was going to get a facelift and botox done, and she did, indeed, look much better afterwards. And I praised her looks, which made her very happy indeed.
Or you don’t even mention it, and ask a third party for confirmation. My mother hates the fact that lots of acquaintances’ first words to her after not seeing her for some time are “oh, my, you’ve lost weight!” No, she hasn’t, so she takes it as showing that they remember her fatter.
Lynn is right on. A general “you look great!” without any questions lets you a) not be an idiot if they didn’t do anything, b) lets them think they are pulling off a two cup increase in boobage with discretion, c) lets them talk about the work if they want you to know.
I didn’t know how to respond till I saw Lynn’s answer. Yet another thread nailed on the 1st post. Some people will want you to know every gory detail, some would rather keep up the facade that they’re just soooo well-rested lately!
