*I hope MUJI does not mind me using their product image.
Of course, I am not paid for endorsing their product!
I have particular favorite things to buy from Japan. One of those is an undergarment sold by MUJI that has brassiere attached to it. Usually, I purchase two-three pieces of them to enjoy in India.
This year, MUJI renewed the product that contains 22% silk, yet the price remains the same; 1,990 yen. Until 8th May 2017, they are running a special campaign for MUJI members (that I believe you can become very quickly over the counter) to avail them all the products with 10% discount. Also in the same period, if you buy two or more pieces of certain products (including this undergarment) you will be granted 20% discount.
I sampled one yesterday and it was so comfortable that I felt as if I was not wearing anything inside. The touch of the silk and cotton fabric was tender and it would be nice in the weather like we have in India. Highly recommended!

I got the one with navy blue colour.

Inside fitting is also comfortable.
