I see this as a situation similar to when you see a woman with a big belly, you don't know whether you should ask when she is due...
If you are not good friends with this woman, it may be best left alone. You don't know how they are going to take such an offer. I don't know how I'd take that offer if someone was to ask me if I wanted makeup lessons or a makeover either especially when I was not hinting at wanting one. I'd probably take it as an insult no matter what that other person's intention was. I once offered fashion advise to who I thought was a friend. I told her that her pants with the really large gusseted pockets in the back made her look like she had a big butt. What I thought was a favour to her, she took as an insult that I was saying she had a big butt. Go figure...
