Well, if you want Pakistani designers lawn and that kind of stuff the budget of £120-150 isn’t really off. If its the non-branded kind of clothes or even the ready made ones from low end brands like cynosure, generations or khaadi etc £40-50 might work as well.
For the rest of things that you need help designing, it would be difficult to say anything without the pictures. If you can inbox those pics, i’ll be able to comment.
