But all the op has said is that her clothes are unusual for the season, but you go on to say she doesn't wear gloves, tights or scarf, really? Surely that's personal preference? Perhaps if she is very overweight she struggles to find nice clothes to fit? Or she gets very hot and sweaty, could explain the BO too.
Her hair is unflattering, well frankly it's up to her how she styles her hair.
She wears no make up, it isn't the law to wear make up either.
She smells and has greasy hair, BO isn't always down to bad hygiene, fact, I have been educated on this by seeing my poor dp showering 2 and 3 times a day, trying every deodorant on the market, and still having a problem, made worse when he's hot or anxious.
I suffered terribly from greasy hair and acne in my early 20s, I am very clean, it was hormonal, age and the pill have resolved it nicely.
Maybe she is just a dirty mare, but people trying to diagnose depression through a third party online seems a bit much.
I have worked in an office with people who have body odour, seemingly poor hygiene, nasty perfume, stinky of fags, bad breath and all the rest. But to be honest, unless you're 100% sure or it is affecting their ability to do their job, I think that you have to tread very carefully.
Now you're saying that you're concerned that she's not able to fulfil her role because of her weight?
Sorry but this just sounds like a botch about someone who isn't as preened as all the other office girls. Just my opinion.
