Replying to Holden Size

Okay so im looking at getting a Holden suit for next season and decided on the Declan jacket in blue and Everett pant in charcoal.  But i am stuck between what size to order.  The jacket is available in medium and x-large and im worried the medium will be short in the sleeves and overall length but think the xl would just look dumb since its supposed to be a more fitting jacket.  The pants are available in medium and large and im not as worried about these sizes because im i dont mind the pants being tight but a medium with xl would look stupid.  I am 5'8"-9" and 140-150lbs.  So i just want peoples opinions and if youve tried either on or have them i would appreciate it if you could let me know how they fit.  Thanks in advance
