Unfortunately
we do not know of any individuals or businesses that produce traditional
Lao wear in the US as this information is not readily available
to us.
I do recommend
that you try to contact family members or friends in Laos who would
be able to contact a local seamstress or tailor who would be able
to create the clothing for you and your future-husband and send
it to the US.
Another suggestion
is to simply ask around in your nearest Lao community. Often times
there are at least a few people who have Lao fabrics and who may
know how to sew Lao wear - this is definitely something I would
try first, if you are unable to contact friends/family or suppliers
in Laos.
