To be annoyed with ladies clothing sizes?!

On the other hand , it doesn't suit me. I look really frumpy in their clother

Because every single person has a unique body and what fits one size 10 might not be the best fit on another size 10.

Just buy what fits your body best, who cares if the label says 10 or 14?

I'm the same I've lost 50lbs in 3 months. I was size 20/22 in primark leggings and tops. I'm now in 14/16 in leggings and 18/20 in tops (vests are 16/18) but went to get jeans not even size 20 would fit went to asda size 22 don't fit either size 24 was to big.

But their jeggings and leggings the ones are £9 size 16-18 fit.

I'm 5 ft 6 and 300lbs and

It's a thing but it's just never bothered me. I do think woman see the size label as labelling themselves. Despite my best efforts I've got around 40kg to lose. The clothes in my wardrobe range from size 12 to 20! I just buy what fits. Normally pick up a 16, if it looks my size I take it into the fitting room, if it looks skimpy I take an 18 and a 20. I agree with someone earlier who said it's a millennial thing. (I'm 57 though). My 21 year old daughter is a very petite size 10. She likes everything oversized though and thinks nothing of buying a jumper in an 18.

I think there are two problems with what you are asking for, though I completely understand where you’re coming from, since just like everyone else, I have clothes ranging from 10 to 14 in my wardrobe. Firstly, each shop uses a different body type as a standard - athletic, slim, curvy, older etc, so what fits in a 10 in one shop won’t look good in another because it’s designed for a different shape. So your New Look jeans are designed for a particular shape that happens not to be you. This is a good thing, because with the variation of stores, mostly, different body shapes are catered for - I know, for example, that Hobbs will fit like a glove, but Zara will not let me have boobs unless I buy L or XL (which will not work for the rest of me)

Following on from this, I was one (healthy) weight throughout my teenage and uni years, lost some weight starting work, gained some with age, then dieted it off to be my teenage weight - then was very dismayed to see I still looked a bit chubby, because the ratio of muscle and fat has obviously changed with age, and I am much less muscular, toned and a very different shape after having a child. Literally, your hips and ribs get wider due to the weight you have to carry. So to expect that you will always be X size in all shops throughout your life, and that neither your body nor the template size measurements will change, is perhaps a bit misguided.

I'm a 12-14 in most places. In H&M I'm a 20 make that make sense.

OP Well you've discovered how your body has the ability to change through life. A garment with stretch (like a jumper dress) will always be more forgiving to a something with a fixed stiff waistband, as will something floaty. You keep mentioning your relatively small size and now you talk about abs so you are obviously body conscious. If the biggest problem you have is that jeans from (only) one shop don't fit you despite bigger sizes are available you are very fortunate. I also get the impression you are enjoying the debate and attention on here 😉 a stealth boast perhaps

I span size 8 - a pair of trousers from Toast, luckily all the reviews advised to massively size down - to 16 - a jumper from M&S. admittedly to allow the inevitable shrinkage even after hand washing.

I’m a solid size 12.

This is why is really pisses me off that places like asos are charging for returns. If I genuinely don't know if I'm going to be a 10,12 or 14, or whether I need normal length or tall, I have to try them all.

I agree. It is odd.
I never buy trousers or jeans online. I really need to try them on as they are so varied. I'm a difficult shape - fairly slim but with a big bum and thighs so trousers are a nightmare.
I find sizes for tops more consistent and generally wear the same size top from all shops.

So true! I'm wearing M&S size 10 jeans, v comfortable fit so I ordered a black pair. There's no way I could ever have fastened them. Same shop, same style.
I once owned jeans in size 8, 10 & 12. The 12 were by far the smallest. It's mad, I hardly ever dare order jeans or trousers online now but at least I got my M&S advent calendar...

Well it probably won't be whatever size you've ordered in the past, isn't that the whole point of the thread!

How funny, I never have this problem at all - a size 8 will fit me 99% of the time regardless of where it’s from. some clothes are just designed differently and I assume it’s the style as opposed to being ‘incorrectly’ labelled. Different jeans feel different depending on where the waistband lies etc eg if you’re apple shaped and want high waisted jeans, a bigger size would be more comfortable etc.
I will caveat this with the fact my weight/size never changes though so I think that helps.

There’s no consistency, even within the same stores.

Admittedly, I do have quite a difficult shape when it comes to buying nicely fitted trousers. I’m usually an 18 on the bottom but I have a relatively small waist compared to my hips and thighs and small ankles.

I have 3 pairs of jeans on rotation at the moment, in sizes 16, 18, and 20 and none of them fit exactly how I would like. The 18 and the 20 are much too big on my waist and ankles, but the 16 is a little snug around my hips but perfect on my waist and ankles. I’ve tried getting shorter leg jeans to combat the baggy ankle problem and it still doesn’t work! They’re either too short or sort of flare out at the ankle.
If I had the funds to do so I would have all my jeans tailor-made to me 😂

I try not to look at the size on labels anymore, if I’m shopping in-store I just pick up what looks like it’ll fit.
