Short-sleeved underwear in size S/M using DRYNAMIC MESH material. - Brand: MILLET - Size: S/M - Type: Short sleeve - Material: DRYNAMIC MESH Unfortunately, I bought this here the other day, but I gave up on wearing it the moment I opened it. It looked too tight, so I'm putting it up for sale. I am 174cm tall, weigh 65kg, and have a slightly muscular build. My chest measures about 86cm. I usually wear a size M T-shirt, which is about 49-53cm, or a snug fit. But I judged that this was impossible just by looking at it (sweat). S/M sizes are tricky! I opened it to take photos, but it's completely new. Thank you for looking.
