...and part of the secret of having your wash dress looking nice longer is to...not wash it
(so often). We moderns tend to wear an item once & toss it into the wash. 19th century laundry facilities being what they were, clothing was not washed all that often. Unless I end up dumping something disgusting down my front, or having mud up to my knees, my dresses get aired & brushed if necessary - and 'spotted' as needed. I may launder or dry clean once a season and NEVER dry in the dryer!
