Medium is an extra small in western sizes

Please note the medium size fits like an extra small! At 5'4, 140 pounds,  28in waist, the medium size JUST fits me. Overall, I really like this shirt . It is a stretchy fabric, and the colors are quite vibrant. Would definitely recommend.

Like the shirt, it feels good, feels well put together, however...  Medium is too small (or maybe just at medium) All my Tiki/Hawaiian shirts I order Medium and they fit loose, but not baggy loose, just not "Medium is Medium" size.

Anyway, returning and will order a Large. Medium is either too small or no breathing room.

ONE more thing, no pocket!  I'm old now, and wear cheaters, I need a place to put my glasses (Please don't say on a string around my neck...)

The person wears a medium size, but we order a large size for this item and was still a little small.

For those concerned about sizing, the sizes aren't 'wrong', they just aren't 'American'. A medium in america is more like a large in other countries, and this is not from america. I ordered a large as I wanted it big and it fits perfectly. Keep in mind the sizing issue, as its not them being incorrectly sized. I am quite happy with mine, and it came in sooner than expected.

I ordered a men's extra large for my husband.  I am a women's medium and it barely fits.

I was really hoping this would fit me but it was too small for a medium. It was like an extra small on me.

Ordered a Medium because that is what we purchased before but perhaps this one is from another manufacturer because it is too small and very tight fitting. We will need to send it back.

Unfortunately the sizes are not "american sizes"; the XL fits like a "Medium".  Quality good for the price.
I had to return mine as it was very tight.

Like most t-shirts made outside the United States, this extra large shirt is on the small side.  Then, you wash it and it's a medium.

The small is to small and the medium is to big..  UT I love them and wear them anyways.
