This seems unlikely. Clothing is about a $1.3 trillion market, against a world GDP of about $80 trillion. I doubt that an industry that's 1.6% of GDP is contributing 10% to carbon emissions.

Also, as pointed out below, the "fashion industry" includes all clothing. Beyond food and water, I'm not sure what would be more necessary than clothing.

The overwhelming majority of clothing produced is totally unnecessary. The fast fashion industry produces an insane amount of clothing, way beyond what is necessary for utilitarian purposes. I don't doubt that it causes that much CO2 emission, especially if you factor in the shipping cost from the places that manufacture it.

I believe this is generally true of any utility. We can all live of soylent or something instead of moving around foods that spoil easily for example. We could all also live in large concrete block where everyone has a small room and houses don't exist. All of that would be hugely more efficient but I doubt you or many other people would like that.

A bit of an excluded middle - soylent or what we have now, a massivly wasteful and inneficient food system. I, and many others, would argue that localization and diversification of the food system is the missing middle here.
