maikunMens & Womens Canvas Belt with Black D-ring 1 1/2" Wide Extra Long Solid Color

My waist is 37". If I choose waist 36" to 39" will there be enough belt after buckling to tuck through a belt loop 5" from the buckle?

How long is the 31-34" waist (excluding the buckle)?

Does this type of buckle remain tight, or is there any slippage?

I never received my item?
