The only tip I would give is to order a swatch before ordering a bulk of dresses. I ordered the dresses in pink thinking that the colour would be much lighter than it was. I didn't realise I could order a swatch. I contacted customer services about the colour issue and they were extremely helpful and answered very promptly.
This dress was shipped on due date and looks perfect on my mum the shape suits most of women and gives her a red carpet style!
