Of course you can... if you have PRIOR KNOWLEDGE
in the Industry (Garment Technician, Pattern Maker, Production Manager, Design Assistant- woring in retail does not count).
In an attempt to save money, many start-ups wish to forgo any assistance from a Production Manager and do it all on their own. They receive the sample back and it's not perfect and they blame the factory.
NEWS FLASH- it is NOT the factories fault. It is the responsibility of the factory to follow CLEAR instructions given to them by a PRODUCTION MANAGER, and a detailed Tech Pack. This includes instructions for fabric, trims (zippers, buttons, elastic) construction of garments, measurements, sizing, grading, adjustments to samples, packaging and freight.
I see start ups doing all of this on their own, with ill fitting and poorly constructed garments doing the rounds and it makes my blood boil. Please do not be one of these people.
