I'm no FLDS expert, but I don't believe they reject technology in a wholesale way -- perhaps you are confusing them with the Amish?  From the little I've read about this group, they use plenty of technology, including computers, cars, phones, etc.  I took a look at the website you linked to, and on the "about us" page the photo background is of a person using a sewing machine.  I believe the clothes are almost assuredly machine sewn.

Some of the pieces do look quite quaint and Little House-ish, but people who try to be conscious of where they spend their money (and the causes/companies/people they support with their expenditures) may want to investigate the FLDS further before making a purchase.  Again, I'm no expert and am not on a soapbox or a crusade, but there is emerging information about these folks, their leader Warren Jeffs is in prison for convictions relating to sexual abuse of minors and there is evidence that polygamy as they practice it is very abusive to women and to the boys who are cast out to maintain a high ratio of women and girls to men for plural marriages.  I suspect that a good deal of their practices fall far from the standards of most Babble readers and would suggest that (if anyone really does like these old-fashioned clothes) before sending money that supports the sect, readers may want to investigate thoroughly to determine whether they are comfortable supporting them.  Maybe if you want a cute sleeper or dress but are troubled by this group, one could look for an old-fashioned dress pattern at the local sewing store and either make it oneself (or, if you're as incompetent as I am, seek out someone with more skill to make it).
