Would you tell a woman her gym leggings were see through?

Regular gym class. Behind a woman today who was wearing black leggings, looked fine when she was standing but as soon as she bent over they were completely see through, almost like a pair of 30 denier tights. Could see colour and shape of underwear. Would you have told her at end of class?

I was planning on doing but she was chatting to another class member at the end and stayed on for the next class so couldn't grab her outside. Feel bad now but also wasnt sure how she would react??

Thank you @Anarchy99 I will bear this in mind in future 👍🏼
It is a bit of a minefield. I would be aghast if I discovered too late that the bum of my leggings was almost worn through, even more so if I’d been in a class with a whole bunch of women who had said NOTHING 🙈 For me it would be a real failure of the Girl Code.

‘Girl code’ 🤢 Put that in the bin with ‘women supporting women’, ‘the sisterhood’ and other nonsensical claptrap.

I don’t think I would tell her. Simply because, if this was me, I don’t have the time/money to immediately go out and buy new leggings. It would be embarrassing for her and you if you see her again still wearing them.

I would. I pulled over in my car the other day to tell an older lady that her skirt was tucked into her knickers... Why wouldn't you try to save someone's embarrassment.

I can’t believe you actually pulled over to tell her. How humiliating for her! I would have been so mortified that someone did something so dramatic

This.

I am forever grateful to the stranger ( a man) ) who told me I was walking down the street with my skirt stuck in my knickers.

If you would want someone to tell you, then tell her.

I think your situation was different its a wrong way of doing things. I would be grateful for this as well.

The leggings one could be that she wasn’t care or they were the only pair of leggings or she forgot that they were see through or forget to check. It’s not a big deal in a class so no need to embarrass her.
She might come in different leggings next time.

Also, I don’t think anyone deliberately wears see-through leggings. Unless they’re the skin coloured ones with bright underwear.

I always assumed everyone buys leggings intending them to fully cover them but that some are better than others.

And, some people can’t afford the better leggings or to replace them. Leggings are often cheaper to buy than other trousers. Not surprising that poor people are wearing cheap versions, worn out and knees out of shape.

There is no such thing as the Girl Code.

For a start we are talking about grown women, not children. And it’s a myth, as a PP said, on the same lines as the sisterhood.

I think people in general should not take it on themselves to point out personal things. I would assume they would then go home and have a good laugh about having to tell the sad fecker whose dress was tucked into her knickers,

Close friend - I might say something as tactfully as possible.

Other: no.

I once met an acquaintance who was a fitness instructor in the supermarket. She was in her leotard and tights. We had a brief chat (I was facing her) and then she walked off. The tights over her butt were stretched extremely thin and her leotard had a thong-type structure, so not only exposing but emphasising her cheeks.

Of course I didn't say anything! I assumed she knew exactly what her rear-view looked like.

Not for me, but we're all different!

If it was just her underwear I could see through her leggings then I wouldn’t say anything. If she was going commando and I could see more than that then I’d consider giving her a heads up.

Why though? Assuming it was unintentional, she can’t dis anything about it at that moment, surely?

No, absolutely not.

People have mirrors and it's their responsibility to ensure their outfits are appropriate for the activity they're doing.

Now, if someone was bleeding through their trousers thats completely different and they might not be aware and I would discretely point that out to them.

But adults in general are perfectly capable of dressing themselves - lets not nanny people

It’s horrible to see the outline of someone’s pants?

maybe a thong but big pants are fine!

tbh I get more incensed but thong and “cheeky” swimwear. Often get more than eyeful as I am getting it my 40 laps and is hate it.

Agree they reveal a lot more

Thepeopleversuswork · Today 08:35

I wouldn’t. She either

a) doesn’t care
b) doesn’t know
c) actively likes it

In all likelihood she doesn’t really care. A gym class is an informal, often single sex space. You’re not working or trying to make an impression on anyone, it’s meant to be somewhere you can relax and not worry too much about your appearance. Someone taking it upon themselves to tell you you should care could come across as judgmental.

If you were at a formal work function you might have a point but people are supposed to feel comfortable in the gym.

If she doesn’t know all you will do is make her feel shit, she won’t thank you for pointing out how much it stood out.

And if she actively likes it she will think you’re a dick.

Just mind your own business. It won’t cost you to accidentally catch a glimpse of someone’s underwear for a few seconds.

thinkingaboutipswich · Today 08:38

Everyone at the gym now is wearing those leggings that show the shape of your butt cheeks when you wear a thong. I would assume it is intentional. I think it looks horrible and so does my young slim DD but each to their own.
