This is something for the ladies out there who love to shop. How fun is it to find something you like and know that when you return home, no one will have anything like it? I think it's great!
I've also got something else to tell you: each of these stores have an online shop! It is easy to choose clothes if you can read just a little bit of Japanese - words related to color and sizing information.
Maybe you have a friend who can translate these things for you. My daughter helped me. Then what you do is contact a Japan buying service like Goods From Japan, and they will take it from there.
What I did was buy sale items, and I found that for me, the size specifications were very accurate. Everything looked as good as it had on the websites, and best of all, my clothes fit. And what a thrill it was to receive the package from Japan!
