I see this a lot on here but I was a size 12 in the 80s/90s, all of my jeans (pepe or levis if its relevant) were sold by waist size and I wore a 30" waist in them.

I wore 30" jeans but in the 70's. They were 30" waist as they were men's fit generally. You couldn't get women's fit then. I was about a size 12 then. The jeans fit my hips but were big-ish on my waist.

Sizing is so inconsistent now across all brands.and shops I have no idea what a true size 12 or 10 looks like anymore. Even at the same retailer, I can be three different clothes sizes, it is so frustrating having to order multiple sizes. I really don't care what the number is anymore, I buy what looks and feels the best.

HarvestMouseandGoldenCups · 22/01/2026 14:56

Of course they would. Iโ€™m currently a size 6-8. I was also a 6-8 when I was 16. I am 9st right now, I was 8st then.

AuntieGrizelda · 22/01/2026 14:57

It's vanity sizing. It feels better to say I'm a size 14 when in the past you would have been a 18
An American size 14 is the equivalent to a British size 18 I believe

mcmuffin22 · 22/01/2026 15:01

Many clothes stocked a 10 as their smallest size though, sometimes an 8. Nothing smaller. So everything has sort of shuffled up.

Any vintage stuff I've owned has really tight arm holes. Have arms really got that much bigger or did people love to feel like their circulation was being cut off?

TempusFuckit · 22/01/2026 15:04

Funnily enough, I still have a pair of size 12 River Island jeans from about 1995 (in purple velvet haha)

They're a little too small for me and I'm currently fitting into size 10 jeans.

But also - the label says they're a EU size 38, whereas now UK 12s are usually equated to EU size 40.

ReturnOfTheToad · 22/01/2026 15:06

What is a size 12 in river island in jeans now? Every pair is different depending on the denim, the cut or just how they were feeling that day. You can't even say that you are x size in y shop these days because sizes vary so wildly. I don't think that sizes are anything other than a rough guide these days.

Flicktick · 22/01/2026 15:07

My size 12 90s jeans still fit so I don't think they have changed much since then. However I have some size 10 and 12 clothes from the 70s and they are tiny in comparison.

EmeraldShamrock000 · 22/01/2026 13:48

Not much. I have a pair of Jane Norman denim shorts from the 90โ€™s that are a size 8. They still fit on holiday.

I have a vintage size 10 coat from the 60โ€™s. It doesnโ€™t close, Iโ€™d say itโ€™s a size 6 at best.

I was about to post that I recently found a pair of size 10 Jane Norman bootcut jeans that I had at uni 24 years ago. They still fit like a 10 does today.

EiEiOhhhhhh · 22/01/2026 15:08

I am exactly the weight I was in 6th form. Over the years Iโ€™ve gone from a 12/14 to 8/10. Iโ€™ve even (in an expensive brand) been a 6. Vanity sizing as Iโ€™m firmly a 21+ BMI and 170cm

Romancingthestones · 22/01/2026 15:08

Absolutely. A12 back then would be 24-26" waist.

Redcandlescandal · 22/01/2026 15:10

I bought a size 12 BHS skirt from Vinted which is 1980s vintage and has a 24 inch waist.

Butchyrestingface · 22/01/2026 15:11

Yes. I'm 5 ft 2. Was sub 7 stone on my 21st birthday in the late 90s. I was a solid size 8-10.

Put on a lot of weight since. Lost 2 stone in 2013. That still brought me nowhere near my 6.5 - 7 stone hey day of the late 90s. More like 8.5 - 9 stone. This time around however, I was falling out of a size 8-10.

God knows what the situation would be like in 2025 if I manage to lose weight again.

Worralorra · 22/01/2026 15:11

Yes - short answer.

In the early 1980โ€™s I was size 14, and I sewed - a lot, and also worked in a very popular ladies boutique. The patterns I used were Simplicity and Vogue, and the sizing on those patterns matched what was on sale in the boutique (I checked, because people used to argue about sizes back then, too, so measuring the clothes when they came into the shop would give you ideas about which styles would fit people who didnโ€™t fit into the clothes in โ€œtheirโ€ size)

  • UK Size 14 in 1984
  • Bust: 36 inches
  • Waist: 28 inches
  • Hips: 38 inches (these were the max sizes)
  • UK Size 12 in 1984 - all measurements were 2โ€ smaller
  • Bust: 34 inches
  • Waist: 26 inches
  • Hips: 36 inches (again, max sizes)
  • UK Size 12 now
  • Bust: ~36-38 inches
  • Waist: ~29-31 inches
  • Hips: ~40-42 inches (varies)
โ€ฆso not only have the measurements increased, but so has the proportion between them, with waist and hips measurement being fuller in proportion to bust measurement.

Based on these changes, the largest named measurements of size 12 now, is a 1984 size 16 bust, with a size 17 (i.e. in-between size) waist and hip.

As I recall, one brand of jeans back then (I think Falmers) used to send us their jeans in sizes 8, 9, 10, 11, 12, 13 & 14. We didnโ€™t stock anything larger than a 14๐Ÿ˜ฑ. They were the jeans that had white piping down the seams!

I accidentally bought an old m&s size 12 from Vinted. They just listed it as a size 12, and I didnโ€™t realise how old the item was (maybe 90s?)

it has a 26 in waist.

I have an old skirt from M&S which has the old St Michael label, I probably bought it in the 90s. It's from when they put the waist measurements in skirts as well as the size.
It's size 12, waist 26".

When I was in my early 20s ( in the mid 80s) and weighed under 7 stones I was an M&S size 8, I had a 22 inch waist.

If you make your own clothes it's so obvious that vanity sizing means clothes sizes are at least 2 sizes lower than they used to be. With dressmaking the patterns have body measurements as well as size.

Jackiepumpkinhead · 22/01/2026 15:23

Definitely, Iโ€™m back to the weight I was in my late teens/early twenties and Iโ€™m now a size 6, I was an 8-10 back then. Itโ€™s a bit annoying as quite a few shops donโ€™t sell anything smaller than an 8 now.

Coasteroller · 22/01/2026 15:47

I was a 10 in the 90s and am still a 10 now.
Iโ€™m definitely not the same size!

@Worralorra -yes I remember falmers jeans. I liked the fact you could get a 9

christmassytimeagain · 22/01/2026 15:50

No I donโ€™t. The 10โ€™s that fit me 25 years ago still fit me now and I certainly havenโ€™t lost weight

Itiswhysofew · 22/01/2026 15:54

I recently bought a pair of jeans in my usual size, from the shop that I buy most of my clothes from, and they wouldn't go anywhere near me. I was really peed off, but then I realised that it was probably because they had zero stretch in them, just the way jeans used to be when I was young and a size 10๐Ÿ˜„

I was terrified that non-stretch jeans were becoming a thing!

northernplatform · 22/01/2026 15:55

Yes, I found a vacuum pack of old 90s clothes the other day. DD is a size 10 and has happily adopted the Next size 12 low-ish waist jeans.

LaurieFairyCake · 22/01/2026 15:55

My current measurements are 28 bust, 24 waist, 33 hips.

A size 14 dress from the 1930โ€™s is just slightly too big now ๐Ÿคทโ€โ™€๏ธ (my favourite dress, been wearing it all the way through for the last 3 stone loss)

MargoLivebetter · 22/01/2026 15:57

Yes, they would be smaller. I wear lots of vintage clothes and I work on the basis of clothes from 80s & 90s being one size smaller than their modern day equivalent and clothes from the 60s & 70s being two sizes smaller than their modern day equivalent.

So, I am a current UK size 10 and I'm a size 12 in the 80s & 90s and a size 14 in 60s & 70s. Obviously not an exact science, but that is roughly what it equates to - for me anyway.

Bobbybobbins · 22/01/2026 16:01

Definitely. I was a size 10 teen in the 90s and now a size 10 in my mid-40s despite being at least a stone heavier!

OrangeisthenewBrown · 22/01/2026 16:08

Rainydayinlondon · 22/01/2026 14:29

A size 10 used to be a 34 inch bust, 24 inch waist and 36 inch hips going up two inches per size-

Not when I was young! Size 10 in the 1970s was 32" bust, 22" waist and 34" hip. I just about squeezed into a size 10 dress for my sister's wedding, in 1976. I don't have that dress any more, but I do still have a size 12 dress that I bought in 1975 and a Laura Ashley size 10 from 1976. I tried them on a few weeks ago and couldn't do up the zip!

Nowadays I'm usually either a size 8 or 10, sometimes a 12 depending on the brand. I'm about the same weight as when I was 17, but my waist and hips are about 5 inches bigger. I'm 68.

Weโ€™ve lost perspective on what a size 12 actually is. If you want real sizing, you need to look at French clothing.

I donโ€™t understand. French sizing is completely different, so is US, Italian, Swedish etc. How can you look to another country when they use a different scale? A 10 in the UK is a 38 in France, a 36 in Sweden, and a 42 in Italy. If anything I find French sizes quite generous as a 38 fits and Iโ€™m between a 10/12.

Unless youโ€™re suggesting that the French have kept their sizes consistent, which is not the case. They have definitely got bigger, along with most countries. My 38s from the 90s and 2000s donโ€™t fit now, but current ones do. My size 10s from 2000s are also more like a size 8 now.
