AIBU to think my SIL was rude about my clothes?

[UninterestedInFashion]

Over the half term week we saw dh family a few times. A kids birthday party, family bbq and couple of outings to the park and pub.

I admit I’m not very fashionable , don’t really follow it and wear what I like and what suits me. For context this is what I wore each time Kids party : black 3/4 length leggings and striped vest top and converse
family bbq hibiscus pattern dress and sandals
park denim shorts and a vest top and sandals
pub same hibiscus dress (it’s very old I’ve had it years but I love it)

The first time SIL said ‘oh here’s Y2K girl’ and laughed at the dress. The second time I wore it she quietly said to me ‘a spotty dress would suit you better - polka dots are in right now’

When I wore the denim shorts she said ‘you’re brave ! They are very short ! How many years have you had those!’

When I wore the 3/4 leggings she again took me aside and said ‘let’s go shopping one day - you need some wide leg linen trousers not these leggings ! I’m surprised they even still sell them or are they vintage again ‘ and laughed?

I said to her no thanks I’m comfortable and it’s hot so I’m wearing what I like and what keeps me cool. She said ‘come on sometimes we all need a bit of a refresh!’

AIBU to think she was really rude ??? I didn’t feel hurt but just irritated.

I'll tell her to stop remarking on what I'm wearing as it's so negative. I doubt she trots out looking fabulous anyway or is she Kate Moss? Why do some people offer an opinion and be unkind (unless it's complementary then crack on). She sounds a snotty cow.

When I was a young teacher, I received compliments at work for a new outfit and was asked where I’d bought it.

”The M&S sale.”

My HoD, who wasn’t involved in the conversation: “Oh, M&S is all right if it’s just for work.”

I get the impression she knows it was rude and what she was enjoying was your discomfort. So downright spiteful and nasty. If that is wide of the mark and she was not enjoying your discomfort she still showed zero emotional intelligence as she was unable to pick up on how it made you feel. Which I suspect would have been evident.
She is either not nice or not very bright. Or possibly both.

When I was in my mid-twenties, a co-worker (same age) said "oh my mum has that blouse" followed by a smirk and side-eye to her friend. I felt so humiliated.

Exactly! Denim and black leggings are just wardrobe staples!
They are absolutely everywhere on everyone!
I wore both these items this week!

OP ignore her, its utter nonsense, there are way more important things in the world than clothes!
I think your clothes sound absolutely fine, she may genuinely want to "help you" or she may not
I have a lovely striped summer dress 15 years old!
My sister took me shopping once she said it was an absolute nightmare!
I have very little interest in clothes these days but I'm confident that I look absolutely fine!
I work clinically so wear a uniform and gym kit mainly
Occasionally I wear a top and jeans
I have a few lovely bits and people say I look fine and I joke that 2010 called and wants its dress back but I absolutely don't care!
Its rather sad that her confidence may be bound up in her appearance too

Maybe the OP could say 'That's very kind of you, let's take your credit cards for a day at the shops.'

have a girly day out shopping?

Or have root canal surgery, far more pleasant.

Oh, she'd love me then, I wore a dress earlier this week in the heat which I bought at a Midway in India in 1996! Admittedly it's now only worn in the garden, commando style. Many of my clothes are 20+ years old.

But op clearly likes what she wears. She wasnt dragging herself around head down in trackies full of holes and a top that doesnt fit. It’s a dress she likes and leggings with converse.

@ToTheRamen so people on here actually dress so that other people can be happy how they look? 🤯

Some people just have a rotten streak.

You don't need to be irritated, she's just trying to be nice and you should take it the same way. Why not let her take you shopping and push you out of your comfort zone? Bond over some nice shoes, etc
You should just accept everything life offers with joy instead of negativity. If you don't want to buy new stuff she can't make you, but go out anyway and try something new!

Perfect!
