I had one personal experience with this site and my fiancé also had one experience and in both cases, it was an excellent. The site is based in Ireland and is unusual in that they make custom sizes at no extra cost.
After almost making a mistake and buying from a site called Tidebuy (a total scam), a friend recommended Laila Monroe and as me and Sarah were thinking of buying her wedding dress online, I was interested in checking them out. To do this, I bought a "surprise" cocktail dress (Christmas gift) for Sarah and to make sure I got it right, I chatted with them on live chat. I also spoke with them on Skype and at all times, they were very helpful in advising me about how to get Sarah's correct size without her knowing :-) When the dress arrived, it was perfect fit and looked amazing.
That helped us make the final decision to order her wedding dress but, being a traditionalist, I was not allowed know anything about the dress but when it arrived about six weeks ago, Sarah said it is stunning and very high quality with every little detail taken care of. And it fits perfectly. Sarah said she paid about $500 and reckons a similar one in the stores would have cost $1,500++ so $1,000 is a big saving. She also dealt with their customer service and said it was a pleasure from start to finish. Since then, two of her friends have also ordered so both me and Sarah are very happy to recommend Laila Monroe if you are looking for excellent quality, excellent value and unbeatable customer service!
