Normal.

It is normal that there is no trademark on the collar of clover clothes. This is because when manufacturers make close-fitting clothes, in order to prevent the trademark from abrading the user's skin, the manufacturer will not sew the trademark on the collar. Therefore, it is normal for the collar to not have a trademark, so don’t worry.

The clover (adidas Originals) has become the logo of Adidas since 1972, when all Adidas products used this logo. The shape of the clover is like the three-dimensional expansion of the earth, much like a world map, symbolizing the three stripes extending to the whole world.
