Should you size up or size down
Short answer: Size up when the fabric has no stretch and the garment fits close to the body. Size down when the fabric has plenty of stretch and the model is already loose on the body.
The fabric matters more than the number
A tightly knitted garment without elastane has no reserve to give. If it fits tight in the shop, it stays tight for its whole life, no matter how many times you wash it. A garment with five percent elastane, on the other hand, gives way and shapes itself to the body within a couple of weeks.
When you should size up
Size up if you are between two sizes and the garment fits close to the body, if the fabric has no stretch, or if it is a garment that has to be washed hot repeatedly. See bamboo t-shirt for women.
When you should size down
Size down if the model is described as oversize and you want it to fit more normally on the body, or if the fabric has plenty of stretch and you already know the brand well. See bamboo t-shirts for men.
When you are unsure
Measure a garment you already own and that fits well, and compare the measurements with the size chart of the new model. That is more accurate than any rule of thumb, no matter how often it gets repeated in fashion magazines. See bamboo clothing for women and bamboo clothing for men.
The cut matters too
A wide cut without stretch can easily fit well in the regular size, even when the fabric itself is stiff. A narrow cut in the same fabric often needs one extra size to avoid pulling across the shoulders and hips.
Pay attention to sleeves and length
Even when the body fits a size, sleeve length or body length can differ from what you are used to. Always check these measurements separately, especially with models from a brand you have not tried before.
Try the garment in motion
Do not just stand still in front of the mirror. Sit down, raise your arms, and take a few steps to feel whether the fabric pulls somewhere it did not when you stood completely still.
Buy the size you actually use most
If two sizes fit almost equally well, choose the one you typically wear most days of the week. If the garment is for rare use, the opposite consideration can make more sense in the wardrobe.
Frequently asked questions
Is it better to size up than down
Often yes, because a slightly too big garment can still be used, while a too small one can rarely be saved afterward.
Do clothes shrink so I should size up
Only with a hot wash. At thirty degrees the shrinkage is minimal and should not affect your choice of size.
What if bust and waist need different sizes
Choose by the larger measurement and have the rest altered by a tailor. That is easier than the other way around.
