✔ 最佳答案
few years ago i saw some in Giordano .
u may have a look there, and also U2 n UNIQLO.
As these are big companies the tees should be of good quality as well as reasonable prices, though some may have very small logos on the chest.
( There are 3 types of black dyes. 2 of them which are a lot cheaper may cause allergy to skin. Hence don't buy those very cheap black tees as they made of the cheap dyes. )
I know u are asking for 純黑色tee. However for the health's sake, i can only introduce these tees.
Hope it helps =)
