Firstly, make sure you stock or design clothes that have messages with some kind of 'good feeling' message that doesn't really make sense. A couple of examples (off the top of my head; you can use these if you like):
- Big heart is great style
- Just love time like me
Secondly, make sure you alienate most of the small, yet relatively high-net-worth farrang market by supplying your clothes in the sizes (S)mall, (M)uch the same as small, and (L)ek. If your somehow find yourself with some XL or XXL lables, just apply them to some of your Small, Much the same, or Lek items.
Thirdy, if you're going into the trouser market, make sure you only deal with shorts or three quarter lengths. Who would want to cover the bottom part of their legs anyway? That's just craziness.
Some generic advice that can be applied to any type of business here:
1. If the customer asks you if you can do something (custom order, pay today pick up tomorrow etc...) make sure you tell him or her that this simply isn't possible - even if this is actually a standard service you offer. They may look disappointed at first, but if they still pursue the conversation you can be sure they're really interested in your product. The bemused look on the customer's face at the end of the conversation when you offer aforementioned service is a heart-warming experience.
2. If the customer asks for a discount, try and give any reason under the sun to ask them to come back tomorrow. The boss isn't here is a good one (don't worry, they won't know even if you are the boss), or telling the customer that you haven't had enough customers today to be able to offer a discount is another good one. Again, if the customer returns it means he really must like your product.
