I’d say it’s more Medium. Vinted disagrees. AIBU?

I don’t think it’s Vinted… it actually changes depending on what brand you put in. Some will have 12 as large and some 12 is medium

either way… a 12 should not be a large!

It doesn’t… Vinted says a Medium is a 10 and a Large is a 12. Can’t be changed.

I think 8 -10 is small 12- 14 medium 16-18 large and 20+ extra large

This is more accurate

Traditionally, UK sizes would be...
XXS 4-6
XS 6-8
S 10-12
M 12-14
L 16 -18
XL 18-20
XXL 20-22
Sizes vary so much though.

Traditionally, there were no such sizes as 4-6!

I defy anyone to show a woman's clothing label of 4-6, UK size, more than say 25 years old - they just didn't exist.

There's been a 6 for a long time!

How long?

My skinniest of friends were always an 8 - I was a hefty 12!

As long as I can remember, around 1980s. It wasn't commonly found in shops but it did exist in some shops/catalogues. Back in the day I often struggled to get an 8, 10 was routinely too big, but those days are gone (still slimmish, just not as slim as I was!).

RosesAndHellebores · 01/08/2025 17:32

I started work in 1980 and don't recall sizes smaller than a size 8. M&S started then at size 10, I'm pretty sure. At 5'7" and about 8st 12lb, a size 10 was a little tight on the hips and an M&S 12 too big. I was a size 10 in better makes: Jaeger, Alexon, etc, Laura Ashley, also a 10.

At about 11st 8lb, I'm an M&S 14 and was a 12 when I was 10st in the early noughties. I'm not as persuaded about vanity sizing as others.

Aliksa · 01/08/2025 17:39

Dd is size 6 and that’s extra Small. She is 5’7” and 65kg, slender with long legs and long arms and often needs an 8 for length (as there’s a fair assumption slim people are often short also which is a nuisance when you have legs up to your armpits!).

She is swamped by an 8. If you saw her you’d definitely say 8 is too big - so I agree 8 is small, medium therefore has to be 10 and large must be 12.

Which makes me… ginormous?

AnnaQuayInTheUk · 01/08/2025 17:45

@Aliksa I'm not doubting you, I'm just trying to envisage how someone who is 65kg and 5'7" can be a size 6. I weigh less than that and am definitely a size 12. Are you sure you've got her weight right?

Funnywonder · 01/08/2025 17:46

I don’t think size 12 is a large. Those Vinted descriptions of sizing are a bit weird.

I’m also utterly sick of hearing people banging on about vanity sizing. It always sounds so smug and self righteous. Try some clothes on in a shop. Buy the one that fits. Sorted. Who cares if your size 14 would have been size G for Gazebo in 1985? They are just arbitrary numbers. And it’s not as if there’s a reliable template. Every shop has a different version of the ‘same’ size. H&M have different versions of the same size in the one shop ffs. I’ve been everything from a 10 to an 18 in there🤣

Well that says it all doesn't it - as a nation we are much larger but it's now common for women's clothes to be sized as 4-6, or XXS(!).

No, it doesn't say it all. Loads of folk needed smaller sizes, and had to adapt/tailor.

Cinaferna · 01/08/2025 17:55

I'm size 12 and definitely fit M clothes in most shops. Uniqlo M is a perfect fit for me in almost everything. I am overweight.

As PP said - today's size 12 was once size 16. I have always been a 12. But 40 years ago I was 2.5 stone lighter than I am now, so size 12 then must have been significantly smaller.

friendlyflicka · 01/08/2025 17:56

It is European sizes, which in my experience, seem much more predictable.

Limonades · 01/08/2025 17:57

8 = Small
10 = Medium
12 = Large
14 = X Large

Limonades · 01/08/2025 18:00

But some brands are somewhat skewed eg Sweaty Betty where an XS seems a size 10!!

puffyisgood · 01/08/2025 18:00

A modern 'vanity sized' 12 is slightly on the large size for a shorter person at least. For a taller person it isn't really. For a person of average height it's somewhere towards probably the upper end of medium build?

WonderingWanda · 01/08/2025 18:00

I think it might depend on height as well. I am 5'9 and currently overweight and a size 14 which I would say is large. I can be a size 12 if I lost a stone and would still be a size 12 if I lost 2.5 stone which would put me at a perfect weight for my frame (in my opinion).

OneBadKitty · 01/08/2025 18:02

Average height and a size 12 is definitely not large.
In most shops if you are size 12 you will need a medium size and in some shops like Hush which have generous sizes then a small fits well on a size 12 figure.

RhiRhi78 · 01/08/2025 18:50

I’m size 12 and normally buy a medium (although some brands I’m a large). It frustrates me that I can’t ever get into a size 10 - I’m around 9 stone but was a size 12 at 8.5 stone too. Im 5ft3 with a bmi well within range.

Cherry8809 · 01/08/2025 18:51

I think some of the people commenting on here are in complete and utter denial about how big they actually are.

A size 18 isn’t an XL? Lol ok, keep telling yourself that.

Zanatdy · 01/08/2025 18:52

youalright · 31/07/2025 19:35

I think 8 -10 is small 12- 14 medium 16-18 large and 20+ extra large

That’s how i’d consider it too.

Girliefriendlikespuppies · 01/08/2025 19:03

Size 12 is not large, it’s very much a medium size.

Disturbia81 · 01/08/2025 19:05

Basically we are all different shapes. Can you imagine if men talked about this stuff..
