An acquaintance (we're not close but get on well) (met at start of lockdown locally and see each other on walks etc) every now and then shaves her sideburns in a very extreme manner which is very noticeable and not very attractive - and also not necessary. She's not particularly "hairy" (NOT THAT THIS WOULD BE A PROBLEM ANYWAY - before anyone says - I'm just trying to set the scene, and also trying to understand why she does it.)
She is single and quite open about wanting to meet someone. She has her eye on several local guys but things never work out and she seems (naturally) upset when they stop calling and don't give a reason.
I'm not saying it's all because of the sideburns - I'm honestly not trying to be nasty - but all in all I just wonder if someone should say something to her along the lines of "gosh your sidies are quite trim - you looked lovely before, you know - I'm not sure you need to do it again next time" or something else? (Please do suggest!)
I'm just at a loss as I feel someone she trusts should say something but most of the mates she talks about are men and she has a brother, so maybe men are less likely to talk about it.... Please don't jump on me for that statement, I'm just theorising.
I would far rather not say something as it's awkward, and I don't want to upset her, but then again maybe it's the kind thing to do?
For example if it was me I think I'd like someone to discreetly take me to one side and let me know they can see I've shaved and it looked better before 
Help!! From someone who really does want the best and has no ulterior motive - promise!!
What would you do?
