<human>: I have a problem that is relatively minor, but it's making me really sad so I thought I'd ask for advice.

My mother, who is wonderful, has lost a lot of weight over the past few years and is understandably delighted with her new body. (She was always very slender, then she had kids and retained a good 30 extra pounds.) 

I love her very much and am very proud of her success, but the problem that has arisen is that she totally retooled her wardrobe and some of the things she now wears are INCREDIBLY unflattering for her body shape. 

I know this makes me sound like an asshole -- and that she totally has the right to wear what she wants-- but she is a woman who values her appearance and tries hard to look good. She prides herself on her style. For whatever reason, though, she has seized on this one sort of outfit (leggings + long, tight shirt + narrow belt) that makes her body look really oddly shaped. This isn't just me saying it -- other people, my not-fashion-conscious father included, have brought this up. It seems like it's just an objectively bad look.

It makes me really sad to see her wearing things that make her shape look weird. She is an awesome lady and I don't want to hurt her feelings, other people have been noticing (and commenting to me) how "interesting" her new outfits are. I don't want her to be embarrassed if an acquaintance makes an unkind comment to HER: she would be absolutely devastated. She associates with people who might be assholish enough to do this, so this is a possibility. 

So, I'm looking for advice: do you guys have any strategies or scripts for gently guiding my mother away from this look? I know that some hurt feelings are probably inevitable, but I really want to minimize the blow to her ego.

Can you provide a brief overview of the text?
<bot>: My mother has taken to wearing some seriously unflattering outfits-- enough that people are noticing enough to comment. I'm looking for a tactful way to let her know that it's not a good look for her.
