1) What are you looking to have made?
2) Details-size, dimensions, colour, artwork, thoughts, ideas. The more detail the better
3) How much are you hoping to spend?
Determine your proper pants size using a pair of pants that fit well and could stay up without a belt. If you are unsurealways, go with the bigger size. Like tailors, we can always remove material but can never add more.
Be as specific as you can. Pant size 32 but a 31 would fit better if they made them? Put that.
