This was my first order with spacelines, so I wasnt sure of the sizing differences which are specific to your brand. So the XS top fits me but the XS pants are too tight. As you only allow one round of exchange, I am now stuck with a pant which I cannot wear. I have even offered to pay for the logistics, but I was still declined. All other brands offer size exchanges, that is a basic service. this is a waste of my money.
