The welcome party will be cocktail attire and the wedding itself will be black tie optional.
For the guys, that would mean a classic black tuxedo. While any black tie tuxedo will work, below are some helpful tips for a cost effective option:

-You can go to Men’s Wearhouse and rent a tuxedo; reference our group #13120103.
– If you join their free Perfect Fit program, you can save $60 off of the tuxedo rental cost.
– When you go in stores to get measured, inform them of your travel dates so that you can pick up a tux prior to traveling to Greece and have ample time to return it when you’re back in the US
– Note that they typically charge a late fee but we’ve negotiated a fee waiver as long as you return the tux within 18 days of pickup.
– Use reference #25136418 to apply the fee waiver for a late return
– If you order online, they will waive the fee automatically with that reference number. If you order in store, they’ll charge you but you just need to call/text Men’s Wearhouse at tel:8662110831 with that reference and group number to receive a refund of the late fee to your payment method
