What should I dress my husband in for Chuseok?

I want to buy them some new clothes for Chuseok~

Where can I buy comfortable suits these days!

Since department stores or custom-make it, I won't wear it many times.

They say it feels too burdensome and we should just buy something comfortable to wear, but I don't know anything about this.

It's to the point where I'm called a fashion terrorist.

You always buy me the clothes exactly as they are on display, but this time I want to do some research before buying.

I want to make my husband look dandy. Where do you all buy your husbands' clothes?

Mainly lightweight blazers / simple shirts

I would like to purchase.
