Deceptijon

I have a 34 in the Edwin 505 sen with the cinch is their a way for me to alter the waist to fit on my waist

I recently bought a pair of EDWIN SELVEDGE SEN in a size 34 .I usually wear a 33 in naked and famous.The Edwin's fit very big and when I walk they fall a bit too below my waist to the point they are uncomfortable.Should I get these tailored to fit better or find away to exchange these for a 33
