Bottoms up...and in...and in

Easy:

Madras capris about 15 years old, formerly 18s with a back elastic/front drawstring waist now slimline with a side zip.

Easier: 

Slightly too long cargos shortened - thrift store 3.30GBP find: tags still on ‘em so never worn.

Easiest:

And the most satisfying refashion of the month so far !
