Mostly for the ladies but men can answer to

I always thought they were 2 sizes away. e.g a UK size 4 would be a US size zero.

Ah that would make more sense!!

My body shape has also changed, although I think it has a lot to do with my age too.

When I was 20 I weighed 133lbs, and fitted comfortably into a uk size 14 in trousers and 12 in tops. I'm a bit heavier now, but wearing a smaller size, and brands that would have been a strange fitting on me before now fit me perfectly. Even my shoes are too big now!

I always thought the UK and US were one size out, like backinthenines. Thanks for clarifying!
I'm 5'6" 147 lbs and UK size 12.

I was always slim (to the point of being too skinny!!) until I hit about 18... Then I started going out for dinner and drinking alcohol a lot more etc... I got an office job after Uni and generally did little exercise

By my mid 20's my weight had crept up and aged 26 I lost almost 36lbs to get down to 112lbs... I wasn't thin (I am only 5ft 1in) but I was a UK size 8/10 and still had a figure (waist, boobs etc..)

Gradually my weight crept up again so I put on 18lbs of the 36lbs I lost... And here I am again!!!

Ideally anything between 112 - 117lbs is my goal.

I never want to be skinny, growing up I had no figure to speak of and that is not my aim. I am not a teenager any more.

I currently wear a size 12 (UK) bottom and size 10/12 (UK) top - although today I have on a tight sweater size 8 (UK) - I guess this sweater 'grew' with me or is vanity sized though as there is no way - even at 117lbs - I am a size 8 on top!! LOL

I totally envy your size 12--and your height!! Sigh. I will look in the mirror (and my closet) and remind myself that if I were 5'6 I would be curvy instead of fat.

5'3
201 lbs
US size 20 pants
Women's XXL shirts

5'6
210 lbs
size 12 pants (can differ a little depending on style/store)
XL shirts usually (also differs like pants)

I am 5'4" and 160lbs and wear a size 8 or 10. It really depends on where you carry your weight.

I am 5'2 and was 195 at my highest weight and wore a size (12/14 US sizes)

Now I'm 148 (24% BF) and wear a size 6 in dresses, 8 in pants and jeans, Small/Medium in tops

I have a lot of lean muscle so I'm heavier than I look.

I'm 5'5 273 and I wear 22s. At 310 I was still a 24 and I will probably be a 22 until I am about 240 or less. I figure I will be a 14 at 180 and if I can make it to the 150s I will be a 10 or 8. Fingers crossed!!!

Height: 5'4
Weight: 153
Size Pant: 10
I miss being a size 4... but I dont even care to get down to a 4 anymore; Happy with a 6 or even 8.

This is really interesting! I'm 5'6.75" and weigh 147. Currently wearing loose size 6 jeans. My 4's are tight but I can get into them. A few years ago I weighed 140 and my 4s were comfy. That's what I'm aiming for again Shirts are small since I have no boobs anymore. I don't wear dresses much. My LBD is from Wal-mart and is size small, but is getting big on me. Sizing is so messed up!

5'7", 157 pounds, wear US size 10 pants and jeans usually but a 12 sometimes (never never an 8 yet), med or large tops unless it's some kinda crazy drapey top with lots of extra room for my sizable stomach (I have 2 or 3 smalls in my vast closet). Dresses are hard for me to fit, even though I absolutely love buying and wearing them, because my shoulders/boobs and legs are both way smaller than my waist, but I usually land around a sz 10 there too.

Vanity sizing has gotten out of control--women's clothes are so much bigger than they used to be. I still have a couple of US sz 12 skirts and pants in my "goal box" from 5-10 years ago that are not even close to buttoning, so I am more like a 2001 size 14. Given that this has occurred, my goal size is smaller than it would have been. I would be really happy to know that any US sz 8 at any store would always fit, and sometimes get into a US sz 6, with medium and small tops. That's what I'm aiming for. I have no desire to ever return to a juniors department, because I am a grown woman--the cut is not right, even if you're skinny.

ETA have gone back and read all responses. It is truly stunning--that some people are wearing the same sizes as others weighing 50 lbs more or less. Just goes to show what a difference body shape makes, how different various makers' sizing is, and how differently people wear their clothes. (I can easily get an 8 buttoned, but it looks BAD and there is major muffin top so I would never say it fits me.) Now I would like to see us all in a room together to see how our pants fit. LOL

5'11, 136 lbs, size 4.

Im 5'7", 182 lbs, size 12 on top 14 on bottom.

5"3 193 #'s I wear a size 14 in pants an L/XL in shirts

I'm 5'6" and was a large size 14 at 180 lbs (some of my higher riding jeans were a little too tight at the waistband). Now I'm a small size 14 at just under 163 lbs (some of my lower riding jeans are a little too big at the waistband). Last night I managed to squeeze into a pair of 12s for the first time in a lot of years.

Okay I was just beginning to think I was like someone else because I am 5'6", was 184 and have worn a 14 for years. I am now about 167 and can easily wear a 12 and bought 2 pairs of size 10 dress pants at Talbots to wear to work until spring. I was actually pleasantly surprised that the 10's fit because they are a high waist style and my waist is larger than my hips proportionately. On most size charts my hips are an 8 or 10 but waist 14 or more. But there is a ltitle stretch. I wore the brown pair on Monday and black pair all day yesterday and they were very comfortable.

I do notice though since I eat better I don't get much bloating so I haven't encountered pants digging into my waist in a long time!

I hope to buy size 8 for my summer pants/shorts. My favorite stores are Ann Taylor, Eddie Bauer and Talbots. Their clothes fit me well. I can now buy a size medium top at all those shops but am still wearing a lot of my size large tops even though they are kind of big on me.
