What regular fit means and how it differs
Short answer: Regular fit is the middle fit. It follows the body without lying against it and without being loose. It is the reference point that slim and loose are described against.
Between slim and loose
Slim fit lies closer to the body, loose fit hangs free. Regular fit is between them and is the fit most standard sizes are built on. See bamboo T-shirts for men.
What it means in practice
You can take a flat grip of the fabric at the side without it pulling, but the fabric does not hang loose. That is the practical test.
It is not a standard
Regular fit does not mean the same across brands. One brand regular can match another brand slim. Measure rather than trusting the word.
Compare with something you have
The safest method is to measure a piece you already own and compare with the chart. See bamboo T-shirt for women.
Shrinkage changes the fit
A regular fit piece that has shrunk becomes slim fit. Wash at 40 degrees. See washing and care.
