A size 12 is generally a Medium (M) in Australian sizing, converting to a US size 8 or 10, a European 40 or 42, depending on the brand, and often equates to a UK size 14 in dresses but a US 12 in some general sizing. Key measurements for AU 12 are roughly a 92-96cm bust, 76-80cm waist, and 98-103cm hips, but always check specific brand charts.
(For example: Size 12, XL.)
An Australian size 12 is roughly a US size 8, UK size 12, and European size 40, translating to measurements around 97-101cm bust, 78-82cm waist, and 105-109cm hips for women's clothing, often considered a Medium (M). For boys, an AU size 12 fits a 68cm waist and 150cm height, while kids' sizes can vary.

In Australia, a size 12 is generally considered a "straight" or "missy" size, falling within average ranges, but due to vanity sizing and inconsistent measurements across brands, it can represent different body sizes; health-wise, a larger waist (over 88cm for women) is a risk factor, and the actual average Australian woman is now closer to a size 16-18, meaning a size 12 is smaller than average, though "fat" is a subjective term related to body image and health metrics like BMI, not just a single number.
Using a one-size-fits-all size chart across different product categories is another common pitfall. Different products, such as shoes, shirts, and pants, each have unique sizing requirements that a general chart cannot accommodate. A lack of specificity can lead to incorrect sizing and, consequently, increased returns.
Plus-size clothing is generally considered a women's size 18 and beyond. “Missy” or “straight” sizes range from 00–16/18, XXS–XXL, whereas plus sizes range from 12W–28W, 0X–4X and greater. You might think plus sizes are just extended straight sizes, but guess again.
size 10: 36-28-40 (B:+8 W:0 H:+12) size 12: 38-30/31-41 (note: bust increases 2″, waist is 2″-3″ over size 10)
70kg isn't inherently heavy for a woman; it depends heavily on height, body composition, and build, but it often falls into a healthy range for taller women, while for shorter women, it could lean towards overweight. For example, a 175cm (5'9") woman at 70kg has a healthy BMI, but a 163cm (5'4") woman at the same weight might be considered borderline overweight, according to this article from The Daily Telegraph.
Whether 80kg (176 lbs) is "heavy" for a woman depends on her height, body composition (muscle vs. fat), and frame, as Body Mass Index (BMI) can categorize it as overweight or obese for shorter women but might be healthy for taller individuals with significant muscle mass, though a BMI over 30 (obesity) is generally considered unhealthy for most. A single number doesn't define health; factors like fitness level, strength, and body shape matter more than just weight.
That being said, to me, generally, for a person who is ~5'5", I would say that "slim" ends at around size 4 , and sizes 6-8 are then "average" or "standard" or whatever you want to call it. Size 10-12 would read as "curvy" to me and then sizes 14+ would probably read as plus-sized.
A size 32 in jeans typically refers to a 32-inch waist, which often converts to a women's numerical size 12 or 14 (especially in US/AU sizing) or a UK size 14, but it can vary by brand, so always check the specific size chart. For women's clothing, a 32-inch waist usually falls into a size Large or XL range, around a US 12-14 or AU 14.
