Vanity sizing meaning and why your size changes between shops
Short answer: Vanity sizing meaning is simple: a brand gives its clothes a smaller size label than the real measurements suggest, so you can feel smaller in one shop than in another. That is why you can be a medium in one place and a large in another.
What the vanity sizing meaning is in practice
There is no single size chart that every brand follows. Vanity sizing is when the size label drifts smaller over time than the real measurements say. That means a size 10 at one brand can have different measurements from a 10 at another, so the number is not a reliable yardstick.
Why sizes are not the same
Brands have different customer groups, cuts and sets of measurements, and nothing requires them to follow one system. That is why one medium can be snug and another loose. At one brand a T-shirt may be cut short and close, while at another it is long and stands away from the body.
How to find your size anyway
Trust the measurements and not the label. Measure your bust, waist and hips and compare with the size chart for the specific garment. Browse bamboo T-shirt for women and read the measurements for each size before you choose. It is the surest way to avoid wrong buys.
Measurements and fit are two different things
Measurements tell you how large the garment is, but not how it sits. A loose cut can be worn in several sizes, while a close cut needs you to hit the right one. Think about how close you want the garment before you choose a size, and not only by what the number says.
How the fabric affects the fit
Bamboo in clothing is viscose from bamboo, which can give a little and drape softly. A stretchy fabric forgives small differences, while a stiff one does not. If you are between two sizes, the best choice may depend on whether you like a looser or a closer look and on how the fabric is woven or knitted.
Underwear and bras follow other rules
Bra sizes are built from both the underbust measurement and cup size, and they cannot be compared directly with T-shirt sizes. Measure yourself and follow the brand guide. See bamboo bra without underwire, where you can read more about how sizes are built and how to find a comfortable fit.
Ask for measurements when you shop online
When you buy online you cannot try the clothes on. Use measurements and reviews, and read what others write about the fit. Order two sizes if you are unsure and send one back. Check your right to return, so you know which terms apply before you order.
Keep your own measurements
Write down your measurements and update them when your body changes. That gives you a fixed starting point whatever brand you shop with. It gives peace of mind, and you do not have to rely on numbers on labels. Jogging suits, T-shirts and other everyday wear get easier to choose, see bamboo jogging suit for women.
