(Let me preface this by saying, I receive no compensation of any sort, for this recommendation - I just found that there was a lot of useful stuff in this book...)

Awhile back, I bought this book: How to Get Dressed: A Costume Designer's Secrets for Making Your Clothes Look, Fit, and Feel Amazing. The writer, Alison Freer, does costuming for film and television.

There was a lot of great stuff in this book, but I thought the laundering tips were what really made it worth my time and money. I now hand-wash a lot of very delicate pieces (lingerie), expensive pieces (Wolford), pieces that will gradually stain and discolor (swimwear), and older machine-washable pieces that I want to stretch the life of, because I have not found replacements.

Anyway, let me walk you through my process, taken from Freer's tips...

1) I always wear close-fitting rubber gloves, because my hands and nails get very dry and look awful. It also keeps my cuticles or a rough nail from snagging the fabric

2) Depending on the garment, I fill the sink with cold or warm water, and immerse the garment. I use natural soaps, like Dr. Bronner's or Trader Joe's Tea Tree Soap, or Shea Moisture bar soap. These all seem to rinse well, and not leave residue, and my stuff always has a light, fresh smell.

3) I start with the parts of the garment that are in direct contact with my body: underarms, collar, straps on tops and bras, and the gusset + feet of undergarments and hosiery. I smooth the soap onto the area, and rub the material gently between my fingers. Then I gradually work the soap through the rest of the garment. I do this for five minutes (Freer's recommendation), and then I rinse 2-3 times, still rubbing the material very gently through my fingers, to make sure I'm getting any soap residue out of the garment.

(I try not to use too much soap, or overfill the sink. I use just enough water to cover the garment. The last batch of rinsewater, I usually re-use for the next item or items, if I'm washing multiple pieces.)

4) Then I roll the item up in a towel and press down on it or stand on it, to get all of the excess water out. I either put the garment on a sweater rack, or hang it up to dry.

This technique has worked for so many of my pieces - and surprisingly - has improved the appearance of clothes that I've previously washed in the machine, whether it was permanent press, delicate cycle, or the hand-wash cycle. I still wash items in the machine, but I wash my Wolford pieces, hosiery, undergarments, and anything I can't replace, in the sink. It's been especially helpful in getting sunscreen out of my swimsuits before it has a chance to really set in and stain the suits.

I love that I can get more frequent wear out of favorite pieces, because they usually are dry by morning, and it's really great to be able to wear the very pretty lingerie, and not be caught up in a backlog of waiting for a full load to run the wash.
