Note down the style and clothes you’d like in your boutique. Create lists of ideas and your thoughts. Be practical and logical. While you may love a particular style, is it one that will attract sufficient customers in your area? For example, you may love hippy gear but how many hippies are in your area waiting to buy it?[1] X Research source
Look online to get an idea of the costs involved for different styles of clothing, at manufacturing and designer sites for retailers. What sorts of mark-ups can you reasonably expect to charge to make a profit and still get customers?[2] X Research source
The budget needs to cover rent for the store, insurance, power/water, stock, clothing racks/hangers/display units, etc. and such items as lighting, cash registers, card payment facilities, carry bags, advertising, etc. You’ll also need money for staff and cleaners.
Consider working toward having both.
If you are going to be selling your clothing online, then check out sites such as eBay and Etsy.
You’ll need design specifications if you’re asking manufacturers or designers to make clothing to specific requirements. Always ask for test garments first, to be sure they understand what you’re seeking. Consider hiring local sewers if you’d like to help people in your area make a living. This can be an added selling point if you market it well.
If selling online, develop a recognizable online brand for your clothing sales. [9] X Research source
Remember that job advertisements will cost you, so add these into the budget. Make the job requirements absolutely clear in the description.
If opening an online-only store, use social media to encourage customers to visit; you can still have opening sales. You can even have a local party which is then reported online to all viewers.
