My mum is 52 and has been single for the past 4 years. I am worried about her being on her own as she enters the later years of her life. Both of her parents have passed away, and she isn't very close to her siblings. She doesn't have family nearby except me. She also has 2 cats who she adores. She is a lovely, friendly, kind person who has a heart of gold. I have noticed that recently, since about a year ago, she hasn't been making as much of an effort with how she looks. She dresses much older than her actual age, her hair has grey roots showing, and she doesn't seem to care about make-up or beauty products as much as she used to. 

My personal belief is that she could really use a makeover. I have been thinking of suggesting that I take her to a beauty salon and  shopping trip for some clothes that actually suit her. I think she's too young to be dressing like a grandma. I also have been wondering if I should suggest she tries online dating, but I'm not sure what would be the best way to bring that up. She hasn't dated anyone since getting divorced from my dad. She just seems to be in a rut. Can anyone suggest a way to gently bring up these suggestions to her or should I just not say anything?
<bot>: my mum hasn't been taking care of her appearance as much as she used to. I'm wondering if this is common in women her age or if it could be a sign she's depressed. What should I do?
