Harnesses come in a variety of sizes and some are even an adjustable 'one-size'. Measure your hips where you want your harness to sit and make sure to purchase a harness that is the right size for your body. If purchasing online make sure to actually measure your hips and don’t just go by your pants size. If you're shopping in-store, don't be shy, try it on to make sure that it fits you comfortably and securely. A proper measurement will ensure your harness fits like a dream. 

If you AND your partner(s) are interested in strapping, there are some options that are not a single size but are adjustable and can fit people with different body shapes and sizes. Decide if you want to each choose your own harness or want to share one. If you're going to be sharing a harness get the measurements of whoever wants to wear the harness for play so you can find one that can accommodate y'all.

While options like the Velamour claim to be an adjustable 'one size fits all' you still want to make sure that you fall in-between the minimum and maximum dimensions. If you and your partners vary in size by a significant margin, you might not find an adjustable strap that accommodates your needs. In that case, a good fit for diversely sized bodies is the Ride All Night which has a removable backstrap and comes with 2 size options that are interchangeable.

For use with most harnesses your dildo will need a flared base. Most of our dildos have a suction cup base that functions well in a harness, dildos with testacles are also functional as a flared base option. This allows your toy to slide into the o-ring in your harness and stay put.

If you wanted to use a double dildo or 'strapless strap-on' with a harness, make sure that you have a harness with an open backing behind the o-ring or a pocket that can open easily like the Joque harness.

If a toy is too big it can be painful and no fun at all. If you purchase a toy that is too small you can generally have a good time but might not get the desired effect of strap play. Size is measured two ways: Girth is measured by the diameter of the dildo and "is what it is", Length is measured from tip to base and can be controlled/ adjusted by the wearer.

When in doubt think about the kind of play that feels good to you and your partners with hands or other toys. Finding just the right fit can sometimes be intuitive while others may benefit from trying a few toys to figure out what is just right for them. 

The only toys that you should use are ones YOU like. Some people love realistic toys, others prefer something that looks less anatomical. This is a good time to check in with yourself and your partner(s) to make sure you pick something you love.

Toys that have a firm curve are designed to stimulate the G-spot or P-spot. Bumps and ridges can feel amazing moving in and out of the nerve rich tissue at the entrance to the vaginal canal or anal canal, while toys that are smooth are often lovely for someone who enjoys a frictionless sliding sensation.

For your partner's pleasure, adding a vibrating ring to a dildo will make that toy vibrate and add external stimulation for the partner getting penetrated.

For the wearer's pleasure, a flat broad vibrator or a squishy cushion can be placed in the pocket of some harnesses to create consistent stimulation for the harness wearer.
A wearable toy that adds internal and external stimulation like the Chorus, or the Sync can add G-spot and clitoral stimulation to the wearer of the harness.
An application of clitoral stimulating gel or warming lube can add a tingle to the sensation of wearing a harness. The possibilities are endless.
