Fits very tight..

I was very excited to receive my Senchi but unfortunately it doesn't fit me very well. I normally wear size M, so I ordered an M. Sadly the sleeves are too short (it's really pulling when using the thumbholes) and the overall fit is tighter then expected. The neckline feels like it kind of chokes me. Quality feels great, but it feels more like an S then an M to me. Bit disappointing :(
If you read this, size up.

Hi! Thanks for sharing your feedback. Our pieces are designed with a unisex fit, which means the sizing doesn’t always line up with traditional men’s sizing. That’s why we recommend referring to our size chart before ordering.
It sounds like the size you ordered is simply a bit too small for you, rather than an issue with the product itself.
We appreciate your support and hope you’ll find the right size in the future!
