I love Lulu's. I've figured out my sizing, XS in anything wrap and formal dresses, S in form fitting or bodycon. Lulu's pays for all return shipping. I've returned three orders and place one once or twice a month. I've never had an issue if I request a call back and they take 10 business days to refund money after the package is received. They cut off returns after you've had the package for some time but I haven't ever ran into that issue. It seems like a lot of people order items when they're in a rush for vacation and don't fully consider the time frames the store gives you upon check out. Then blame the company for being slow from their own expectation.
Many of the dresses and clothes are high quality and some are cheaper, you get what you pay for. Free people and Lulus brand have been my favorite. I returned a bathing suit for poor quality at $40 and a formal dresses for improper sizing but it was awesome.
Buyer tip: don't order clothes for a vacation 7-20 days before you leave and expect a company to ship everything and refund your money on your time. Read the small print at check out and if you're cutting it close... save yourself the time and worry and don't order it. Find it elsewhere. Amazon prime or shop local.
