Good luck with sizing.
Don’t bother! I ordered a $220 costume from this company. When I ordered they had two different size charts listed on their website. I thought I ordered the right size (M) based on my daughter’s measurements, but it was way too small when it arrived. I emailed asking to exchange for a larger size and they asked for her measurements in inches. I sent them (in inches) and then they send me yet ANOTHER size chart in centimeters saying that a bigger size won’t fit. This was a totally different size chart than what was on the website or what was sent in our initial communication. They offered a 20 percent discount, which does me NO good because I still have a costume she can’t wear. I feel like I got scammed. Don’t bother! Edited to add that after I posted this review, the company reached out and agreed to send me a larger costume in the correct size. However they emailed days later saying their manufacturer could no longer make it in the larger size (which makes no sense at all since the larger size is listed on their website as an option). They then offered a full refund, which I accepted since by this point it had been almost a month of emails back and forth trying unsuccessfully to exchange for the right size. Just a hassle overall and I’m still without a costume that fits correctly, but I did appreciate the refund.
