RadBizz Pant Stretcher - 30" to 59" - Heavy Duty - Instant And Long-Term Stretch

how far can you stretch a pair of pants ?

Can you dampen the jeans after they are on the stretcher?

Will this work on elastic waistbands? I have a skirt with an elastic band that is just a little too tight

Will this work for leggings that have shrunk in the dryer? (Caregiver accidentally threw a pair in the dryer and now they won't go over my hips.)
