Help! What size Gucci belt do I need to buy?

I usually wear a 28/29 in jeans (which all fit below waist) and all my Gucci belts are 36.

 

I have one Gucci Belt and it's a size 32 and I wear a size 0/2 or 25/26 in jeans. I can only put it on the first hole though.. You might be good with a 34. The belt I got is similiar to this one

Hope this helps.

 

Yup, Gucci belts do run small.

From Gucci on-line:
belt size guide
To determine your belt size, measure over the waistband of your pants. We recommend sizing up 1-2 sizes. The sizes provided below represent the length of the belt when fastened at the center hole.

My DH's pant size is 32 and for Gucci belts I get him a 36.
