All 5'3" - 5'5" -- Let's compare weight w/pants size

5'3" here

SW: 270 and size 22/24
CW: 215ish and my 18s are a little loose but not enough to need a 16
Edit: 16s might fit me, but I refuse to pay money for more clothes until I need a 14

5'.2.5 CW 119
26.5 waist 35" around fullest part of hips/butt

In women's I wear a comfortable size 2, in some brands a size 0 and I have a few 00 but that's clearly vanity sizing.
In Jr's it usually a 3 or 5, sometimes a 1 again depending on brand.

SW close to 170..163 my first weigh in. 34" waist 42" hips.. I was wearing a 12 or 14 in womens. Couldn't fit into Jr sizing

I don't mean this to be rude, I'm just curious... but how are your sizes possible? I have the exact same measurements and I wear a US 6 (at 90% of stores)

this is another example of where body fat (more than likely) plays a key role in pants size. The less body fat you have, the smaller the size will be.

No, we have the same measurements. 26.5 inches of muscle and 26.5 inches of fat are the same amount of inches either way. We have the same hip measurement as well.

body fat is not measured in measurements alone. She stated she had 98 pounds of lean muscle mass, so COULD have less body fat, therefore making her sizes smaller. My response was just a guesstimate as I do not know either of your body fat, but generally, that makes a difference.

She stated her measurements, which is what clothing sizes are based on.........

I really wasn't trying to bunch your undies... But, seriously last summer I was 120 pounds wearing a size 6, with 24% body fat, then I gained weight and dropped body fat, i.e. 130 pounds wearing a size 2, with 18% body fat. The weight went up, body fat went down, clothing size went down.

Have you read what I was asking? the OP and I have the exact same body measurements (you know, measurements that are used for clothing sizes - inches around your waist, hips etc) but we wear drastically different sizes. Either she's shopping at a very generous place or I'm shopping at a very ungenerous place. See what I mean?

if you would like i will take a picture of me wearing every size 2 pant I own, including brands since this is seems to be huge issue for you. The brands vary but all standard every day available companies...merona, old navy, american eagle etc. I'm not trying to be rude but it's not like I would have any reason to lie, I've been up to a size 14 and have no shame in admitting that.

What i meant by body composition is shape. I'm high waisted so my waist size does not factor into sizing as much as someone who is perhaps short waisted. i'm also a seamstress and love to sew from vintage patterns. I've seen women with the same measurements but different sizes because of the curve and shape of their bodies.

If this doesn't clear it up for you then there isn't much more I can do
