Taking your measurments for BDSM collars and gear is no different from measuring for clothing or jewelry. But there are a few things to consider when ordering kink gear. Even more so when ordering from Restrained Grace, because all of my pieces are made to measure. Most BDSM gear companies have standard sizes like small, medium, large, etc. I personally feel like this is too ambiguous, and since my products are mostly made to order anyhow, I'd rather make them to fit your body.
Adjustable collars: Provide your exact neck measurement. The size you choose will be the smallest option, and it will adjust 2" larger in 1/2" increments.
Non-adjustable collars: Choose the exact length you would like this collar to be. I will not add any length.
Adjustable cuffs: Provide your exact wrist measurement. The size you choose will be the smallest option, and your cuffs will adjust 2" larger in 1/2" increments.
Harnesses: Provide your exact measurements. The buckled straps will adjust 2" at the neck, and 3" at the waist. 1.5" in any other spots.
Day collars: Choose the exact length you'd like this collar to be.
Necklaces: Choose the exact length you'd like this collar to be.
