A child's size 16 in Australia is roughly equivalent to a small women's size, often around an AU Women's size 8 or 10, depending on the brand, with measurements (bust/waist/hips) being key; a youth 16 is for taller kids (around 165cm), so it can lean towards a smaller adult fit, but always check brand-specific charts.
If you buy a 16 in girls pants, it would be a size 14 in women's.
Most of the time, the women's equivalent of a youth shoe size is two sizes up. For example: If you wear a size 4 in youth shoes, you probably wear a size 6 in women's. If you wear a size 6 in youth shoes, you probably wear a size 8 in women's.
If you normally wear women's shoes and are trying to figure out what youth size would fit you best, the simple youth size to women's shoes conversion: your US size minus 2 = your youth size. So if you typically wear a US women's size 8, a big kids' size 6 would likely fit pretty well.
From looking at the Target size charts (cause they're really detailed and comprehensive) a women's 6 equates to a girls 14.
Generally, a youth size up matches a women's size down. To convert youth to women's sizes, subtract 1-2 sizes. For example, a youth large corresponds to a women's small or XS.
Kids' and women's shoes aren't built quite the same. Youth sizes are often narrower and designed for growing feet, while women's shoes account for a wider range of foot shapes. That's why 6Y might lean closer to a women's 7.5 in some brands (like Nike) or nudge up to an 8 in others (like Adidas).
But the actual answer according to measurements is subtracting 1.5 sizes from your size to find your youth shoe size . I'm a 7 in women! I get a 5.5y in grade school… 5.5 in big kids.
A girls 14–16 plus likely would be close to a woman's size 2P.
XXL is about a women's small and XL is a women's XS Wearing girls tops is easier than bottoms because the bottoms aren't made to accommodate hips or a booty. It's always worth a shot though!
Generally, adult shirts are designed for taller individuals, and as a result, they tend to be longer and narrower than youth shirts. However, sizing can vary between brands, and some may make adult shirts narrower and longer than others.
Women's medium or about size 4/6. 18 in kids is a medium in missies/juniors. I would try to stay to plus sizes in kids jeans (kohls, JCPenney, target) so they aren't long or get juniors short jeans.
An Australian size 16 is typically an extra-large (XL) and corresponds to measurements around a 107-111 cm bust, 83-92 cm waist, and 111-119 cm hips, though it can vary slightly by brand, often fitting into US size 12-14 or UK 16, with variations depending on the garment style (e.g., fitted vs. loose) and brand-specific curves, notes this Solbari size guide, this Clothing Direct guide, this PQ Collection guide, this Yarra Trail guide, this The Wardrobe guide, this Taking Shape guide, this Target Australia guide, this Every Turn guide, this White & Co Living guide, this Rockmans guide, this Forever New guide, this ENNI guide, and this ASOS guide.
14/16 in girl's is a Small in women's. 14/16 is smaller than a juniors size small. Like smaller than jr size 0.
I know these shirts were in the toddler section at Target, but I recently found it in the boys section. Size XL (16) is equivalent to a women's medium or men's small 🙌.
