You may need to size up in a regular-fit T-shirt to get a looser look, but a garment already designed to be oversized may offer enough room in your usual size. Check its measurements and fit description before automatically going one or two sizes larger.
Read the cut before the size label
Regular, relaxed, boxy and oversized describe different shapes, although brands do not use these words identically. A boxy top may be wide but relatively short. A regular tee in a larger size may gain length that you do not want.
Look at the front and side product photos. They can help you understand the intended shape, but remember that the model’s proportions may differ from yours.
Compare the dimensions that matter
Use a comfortable top as a reference. Check the chest width, body length and, where available, shoulder or sleeve measurements. Compare like with like: flat garment widths with flat garment widths, or your body measurements with a body-size chart.
If you fall between sizes, decide which feature matters most. You might prefer more chest room, a shorter hem or extra space for a long-sleeved layer. One choice will not suit every person or product.
Try the fit as a complete outfit
A roomier top changes how your trousers look beside it. Put on your usual jeans or cargos, sit down and move your arms. Check whether the neckline stays comfortable and whether the hem sits where you want it.
If a product does not list the measurement you need, ask before ordering. That is more useful than assuming every brand’s medium is the same.

Frequently asked questions
Should I always buy two sizes bigger?
No. That can make a top much longer or change the neckline. Use the actual cut and measurements as your guide.
Can I size down in an oversized style?
Sometimes, but it may still retain wider shoulders or sleeves. Sizing down does not necessarily turn an oversized cut into a regular one.
