Key ApparelMen's Garment Washed Zip Fly High Back Bib Overall

What length are size 38?

If you have a 38"waist with 32" inseam in regular jeans, what size waist and inseam should you order in the Key bibs?

Are the legs tapered? Or are they like bell bottoms?

Does "key apparel" still make their button fly overalls ?
