G day Every one I’m from Australia and just booked a suite in The Wynn  
Was searching a bit on the net  
And I saw that there is a dress code for the Wynn  
Is this right???
I’ll be there next month and I don’t think I even own a pair of long pants.  

You can dress casual even if it states there is a dress codes it doesn't appear to be enforced.  

I was just there and I didn’t feel that there was a “dress code “. But if you use common sense in how you dress then you’ll be ok. Bare feet and tank top might be questionable.
I wouldn’t give it a second thought
Now some restaurants I can see it …

I will leave the Roo in Oz  
Thanks I understand common sense  
But as long as I can wear nice shorts and a button up shirt I’m good  
Thanks a lot guys big help  
Have a fantastic day

You’re good with that style of dress. In my experience casinos only use their dress code to kick out people who behave badly or who stick out like a sore thumb.

I stay there often... beautiful property with a nice clientele.. the dress code is not enforced but I feel you will feel better if you wear a nice shirt or polo shirt with shorts... dress casual but nice..

Pool attire and athletic wear is fine around the Wynn as long as it looks good. XS usually has a nightswim on Sundays over the summer. Otherwise look your best
