T-Shirt Size, fit and measurement & how they impact your fitting:

In order to create an exclusive look, one must make sure that the clothing he/she is wearing should complement his/her body structure and accentuate the flattering areas. Clothing should be the medium of comfort and exclusiveness. In order to become a center of attention, one must know how and what to wear.

Different body types have different cloth preferences. A woman with a round-shaped body needs to wear an oversized t-shirt, whereas a woman with an hourglass-shaped body should wear a body-hugging t-shirt if she is comfortable wearing one.

Accurate measurement ensures the final outcome is perfect in case of fitting and enhances the outfit as well as the personality of that particular person. For example, if a tailor makes a slight mistake in taking the measurement of a woman’s gown, she might end up looking like a child in a borrowed gown.

Inaccurate measurement might result in tearing or destroying of fabric if worn carelessly. One might even trip and fall if the garment is too long and end up leaving a trail behind.

How are T-shirt sizes measured UK? What Measuring system does UK use?

T-shirts are measured normally using a measuring tape all over the world and UK is no exception. One might even take the measurement from an existing t-shirt if he/she feels fit.

In case of a body measurement, the person should make sure that he/she is not slouching. The measuring tape should be held properly, leaving a centimeter’s gap to ensure proper fitting. The shoulder, torso, waist, hips and sleeves are to be measured accurately.

While taking the measurement from an existing t-shirt, one must put on the t-shirt to make sure it fits properly on the body. After a thorough affirmation, he must place the t-shirt on a flat surface and ensure that it is smooth and uncrumpled. Then, he should take the measuring tape and note down the measurements respectively.

The bust measurement should be taken by placing the tape just an inch below the armholes; the length should be calculated by placing the tape vertically from the collar to the bottom seam. Furthermore, the sleeves should also be measured by taking the tape and holding it in-between the area from the shoulder joint to the end of the sleeves.

These are the common measurement guide that one needs to follow while purchasing any form of clothing directed to the upper body.
