The side seams of T-shirts often twist as you wear them; how about this product?
It is a common experience to be bothered when the side seams twist forward or backward after wearing and washing a T-shirt a few times. Seeing the description mention that it 'preserves circular knitted fabric as it is' makes one wonder how this garment is.
Yes, due to the nature of the fabric, the side seams may twist when stretched and worn, but this T-shirt is made so that it remains comfortable even then.
A circular knitting machine is a knitting machine that knits yarn down roundly into a cylindrical shape. Fabric produced through this method continues as a single whole tube without side seams joining the sides, and because the yarn is knitted while winding in one direction, the grain twists slightly when washed or stretched to fit the body. When worn, the side seams shifting slightly to the front or back is how this twisting appears on the outside.
RYOO's Tubular graphic t-shirts [Off white] is a garment made by preserving this circular knitted fabric as it is[1]. Rather than eliminating the tendency to twist, it is a T-shirt made so that even if such movement occurs when stretched and worn, the wearing comfort does not become uncomfortable[2].
Daily care is not difficult either. Generally, the twisting of cotton knit fabric becomes more pronounced with the strong spinning of a washing machine and high-heat drying, so it is better to turn it inside out, wash it on a delicate cycle, and avoid high dryer temperatures. If you gently straighten the side seams and shoulder lines by hand once before hanging to dry, the shape will settle into place.
hmmm, this description reads more like a choice that takes the twisting as a given and refines the sensation when worn, rather than viewing the twisting of side seams as a defect and trying to hold it back.

The fiber composition and recommended washing methods for this T-shirt have not yet been confirmed.
