Does anyone know of an occasion jacket for weddings/christenings etc. that would be made entirely from natural fibres? I've found jackets online that are marketed as "all cotton", but then you look at the details and the lining is 100% polyester, which makes me so sweaty and uncomfortable. I'm a sweaty person anyway (I have battled this for years) and any synthetic fibres next to my skin make me feel like I'm wearing a plastic bag. Why does all occasion wear have to be lined with this stuff? I can't understand how anybody is able to tolerate it!
