Q856: Tailoring a waistcoat

Salaam, I own a tailoring store and sell mens tailored clothing and I was wondering if I am allowed to sell the following waistcoat.

Why the need to ask the question? It’s a waistcoat and I can’t see any reason for it being haram to make it.

If a Muslim wants to wear it, there might a question of the bright red colour or tashabbuh etc

However, you are just tailoring it and there is no reason why sewing it should not be allowed.
