Qipao / Cheongsam are made of good, but sensitive fabrics. Therefore you generally should be careful when you wear a Qipao / Cheongsam.
Stains can be difficult to remove and thats why you should try to avoid them.
You also should avoid fabric coming in contact with rough or sharp objects, which can
hook the fine weave and cause dulling or frayed threads. Rolling up sleaves
of Asian dresses can cause creasing / stretching.
Laundry / cleaning / iron:
Qipao / Cheongsam should be hand-washed or dry cleaned. In general dry
cleaning is recommended, since laundering detergent and dyes in other
clothes may affect fabric adversely. When washing
always avoid strong detergents and gently wash by hand if possible.
Chlorine bleach should never be used.
Ironing is fine regardless of fabric, but you should put a white damp
cloth between the iron and the dress to avoid softening and color
change. And if you dirty your Qipao / Cheongsam with incaution, you can
cover the blot with a piece of moist cloth and then iron. The cloth can
absorb some dust.
After washing and/or ironing, hang it (preferably in a well-ventilated
area) to cool and dry fully before storing. Also fabric can be allowed
to dry on a white towel.
hand-wash with neutral detergent. Hang to dry where it is not too hot.
Avoid to hang it under the sun. It is best to iron when almost dry, using a white
cloth under the iron. You can use higher heat, but you should avoid squirting water on
fabric (may leave water marks).
be dry cleaned - not washed in water or washing machine. If it is a
bright-coloured fabric, the ironing temperature should be lowered
Cheongsam should be hung on wide hanger and not folded while storing. So
if you want to stow your
China dress for long, make sure that it is
hung up by the clothes rack, especially, the shoulder is crutched
Mothballs may be a good idea, but avoid the campher variety, which can
cause yellowing of lighter fabrics.
