To hang or to fold, that is... the point of this section!
You've spent the money and time on building your incredible wardrobe, so you might as well store your clothes properly to extend their shelf life and keep the ironing to a minimum. So here is a quick check list to look over as you go through your closet!
Wool sweaters and anything knit, FOLD! Hanging these items will stretch the neckline and shoulders, weakening the strength we want our clothes to have. Hanging these items will alter the design, stretching and lengthening in all the wrong places which changes how it fits the body, leading you to the thought of rewashing and drying the clothes to rewind the "damage".
Anything cotton and linen, HANG! Folding these items will cause creases that require you having to iron and we want to avoid that at all costs. Just like applying heat to your hair, applying heat to your clothes has the same damaging effect.
Denim, you could do either way. The material is strong enough to withstand hanging.
Trousers and blazers are to be hung for obvious reasons. Hanging them circulates back to that "avoid the iron at all costs" rule.
Blouses and dresses should more than likely be hung, I think you're getting the point now.
Hang anything silky and light weight, fold anything heavy.
HANG silk, 100% cotton, rayon, satin and velvet. Trousers and dress pants, dresses and jumpsuits, leather, suede and over coats too.
FOLD cashmere, knit, wool. Heavy pants like jeans, cargo (if you still even own a pair), embellished evening gowns and t-shirts.
