The term "big girl sizes" can refer to two different sizing categories: children's clothing for older girls (typically ages 7-16) or women's plus sizes. The correct interpretation depends on the context.
Big Girls Clothes (Size 10 - Medium) Big Girls Clothes (Sizes 7 - 16) Big Girls Clothes (Size 12 - Large) Big Girls Clothes (Size 14 - Large)
14 is probably in the overweight category (depending on height obviously) and is not slim. It's not unhealthily overweight but by no means does it classify as slim!
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.
A women's Medium (M) can be either a size 12 or 14, or even both (12-14), depending on the brand, country (US, UK, Aus), and whether it's a top or bottom, but generally, size 12 often aligns with Medium, while size 14 can lean towards a Large (L), though some retailers use 12-14 as a unified Medium. Always check the specific brand's size chart, as sizing varies widely.
The next size up from AUS Youth 14-16 would be the Women's AUS size 10-12.
Understanding the Difference Between Youth XL and Adult Small: While Youth XL and Adult Small shirts may seem similar in size, there are a few differences to consider. Generally, adult shirts are designed for taller individuals, and as a result, they tend to be longer and narrower than youth shirts.
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!
The large L size in number is the better option if you want a loose and comfy fit. Men with a chest measurement between 40 and 42 inches are suggested to wear this L size in number. For individuals who like a more laid-back and casual style, the big L size in number T-shirt is ideal.
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.
Women are a size 16 average in a country where 2 out of 3 people are overweight or obese. So it's not surprising and it's not a good thing.
