Nothing they sent me fit me to be custom made! Garbage!

They should be fit like skin, but they are not. Their quality and customer service are horrible.

My daughter's suit was perfectly tailored and she's a petite size 0 so I don't think so.

Based on my experience, I think they just have different premade sizes and send you the "best fit" one.
I had two jackets sent. The first washing all wrong and was for a much, much larger person with very short arms. When I complained and resent my measurements, the replacement jacket was a shapeless, straight sack. Neither was anywhere close to my measurements.

That was my experience.
I ordered a blazer and it was the wrong shape and size. They told me to have it tailored.
I sent them pictures and showed them it did not match my measurements, nor the upgraded material I paid for, and they just repeatedly said because their website said to take it to the tailor that meant I agreed to have it tailored. I did not want to pay to have my custom blazer customized.
I provided pictures to my credit company and got my money back.
I suspect this happens a lot too because they put up a fight.
It feels like fraud to me.
I dont think they tried to customize the blazer.
