Just to share I let u come my home and try n then buy. I never insist u to buy or stop u from trying. I let u try as per ur wish but I’m also wondering y u didn’t try then. I thot u know the size after seeing the cloth material. U urself have seen the cloth before decide to buy and make pmt. I have no idea abt size for a 4yo that’s y I let u try see n then decide urself If Im any Profesional seller, I would have straight away said no no change no refund at all as u buy after checking ur self.
