Don’t do it.
I would of considered ordering from this company until I had a terrible experience over a simple sample material order. Total nightmare, they wouldn’t take the samples back, nor offer a refund which is a disgrace, they only offered 40% in a voucher to use against a purchase. No way was I doing that, cannot imagine the hassle you would get if the dress was wrong. NEVER NEVER going to use again, poor and terrible customer service.
