Wow this 3D shaping application will transpose us in any store and make sure we get the right size. I don quite a lot of shopping from the internet and many times I was disappointing that what I bought doesn't fit me and that Medium (M) is different based on the brand.
This will make the buyers happy, the sellers not get so many returns and just a great system for everybody, sustainable and without throwing a lot of merchandise. Great find!
Thank you @nygma.
