Nothing, not my place to say. Very few people can accept a negative remark, plus I don't know that person, maybe they are going through a rough time or have self esteem issues, so saying "sorry but that coat is hideous on you" is just wrong,
I really like the chloe Susanna, and I have tried them myself,a couple of years ago, when they were not an eye watering £800 a pair, but I found them too blingy and settled down with a more subtle marant ones, but I really still admire them,
I think she is wearing them all wrong, the leather leggings with these boots is a bit of an overkill, maybe she should wear them with other outfits,
I only check her blog when it gets mentioned on MN, she has great legs and seems really tall, she really looks good in those over the knee suede boots with jeans, oversized sweater and scarf, and again with the black SW boots and black dress, so maybe these kind of looks work best for her, but somehow the jackets she wears don't do her any favours,
Not everything looks good on everyone,and sometimes its best to stick to what works for you,
