I was going on  a trip and needed some swim trunks and these I could have the same day.  I tried them on as soon as I got them.  Unfortunately they were just a little bit big for me.  I am a size 44 and even when I tied the strings, I could easily pull down the swim trunks to my knees.  I felt they would come off if I dove into water.  They seemed to be more of a size 45 to 46.  So  I returned them.
