I wore it twice. The feel and comfort are very good. The [4] size is equivalent to men's M size, but it looked neat to wear it a little oversized. It's a border pattern with a color scheme you don't see often, and it goes with any color or shape of bottoms, so it's a useful piece. From the product page: This is a crew neck T-shirt with a binder specification, using the original border jersey of ＜ORCIVA＞. It has a moderate amount of room, and the silhouette is easy to wear as an inner layer or as a single piece. The thin border lines and the final finish that expresses a clear expression make it a classy piece that is not too casual.
