Does Kate Spade ship to Kuwait?

Customs exemption: Parcels under KWD 100 are usually cleared without customs duty; above that, the 5% GCC customs duty usually applies.
No VAT: Kuwait has not introduced VAT yet.
Currency: US stores charge in dollars; your bank converts to dinars and may add a foreign transaction fee.

Short answer

Get it through a buy-it-for-me service. The quote below from Kate Spade's own policy explains why ordering to a US address yourself may not work for Kuwait.
