I've ordered from them several times. Overall i think their service is really good! Shipping is swift, sewing time is about 1 week (standard), and the materials are decent (not see-through). The only thing i really dislike about their work is the lace they use.. But nice lace is quite expensive.
One thing to be aware of when you order is their standard height!! They make all their clothes to a standard height of 5'5 or soemthing close. So if you're shorter (like me), make sure to let them know! I didn't know this the first time i ordered.. and my coat arrived much too long for me.
I hope this helps a bit!
