Glue down at the front, depends on what armor maker you have but usually 1 large and 4 small ridges (ata can only fit one large and 3 small ridges due to the chest). Make sure that it sits over the back plate in the right postion, before gluing taped the straps on, wore the armor and looked at the back of the straps in the mirror, once happy I marked around the front of the straps with a pencil. If you find the back of the straps sit too high you can apply some heat and bend them slightly.
