Have been in this industry over 14 years, so we know what you want just feel free to contact our service if you have problems in measuring, we also provide measure guide.
For standard size dresses, we need to put them into corresponding size mannequin to check before sending, only dresses fit mannequin well, then we can send them out, we will take photos of your dresses in corresponding size mannequin before sending, so we can make sure our dresses run true to size.
For custom size dresses, each custom made dress will be checked 4 times at least by 4 different workers before sending, so the error should be less than 0.5'' at most, we have already can't be careful enough.
Please note, only the error less than 1'', then dress can fit well, only error less than 2'', then dress can be altered, but if error is over 2'', then it can't be altered.
At Cetims each dress will fit well if measurements provided are accurate.
