I'm old-fashioned when it comes to bras. I like them in neutral colors and plain designs. No laces, frills and shocking colors. It's for practical reason. I like wearing well-fitting and light-colored tops. If I wear a colorful bra, it will show through. If I wear a lacy bra, it will make creases on my top. I didn't realize it's not easy to find this kind of bra in Japan.
For starters, I didn't know if I looked at the right place. I visited the Shimamura, Entetsu department store, AEON department store, Don Quijote and Uniqlo. They're considerably big stores but their bras are too girly- all lace, foams and frills. They're perfect for those wanting to look nice and cute for their men but that's not my purpose. I just need a simple, plain, white bra! They have plain walking bras but the material is too light it won't cover enough what it's supposed to cover. I don't know if Japan has a special underwear store or something but I didn't find what I was looking for in the stores.
