^ I own 4 t-shirts of hers : Limited TA tour 2015, Limited TA tour 2016, Arena Tour 2016 and the t-shirt that came with the limited version of A BEST -15th anniversary Edition-
The two that have started to get worn out pretty quickly were TA tour 2015 and A BEST ones, you can clearly see that the design has started to crack on both of them and if you compare the A BEST one to the AT2016 one in the last picture you can see that the white fabric of the A BEST one has gotten yellowish lol
I used to wash them just like my normal clothes at 30°C, at the time my washing machine didn't have a "hand wash" cycle so maybe that's why they worn out so easily

But I used to wear them only at home so I am fine with not wearing them anymore haha, i just switched to regular pajamas lol.
EDT : Something just came to my mind now, I don't think I have ever thanked ~angel*ayumi~, thanks to you I saved 7 000¥ because I decided not to buy the DEFEND TOKYO t-shirt after you said its quality was terrible lool
