I need advice and help about making an clothing brand

what type of clothing are you trying to aim for?or more specifically what type of design?I feel like different type of brands need different needs.
if your going for more y2k/grunge type clothing i recommend checking out some stuff from studio2am,but also for blanks you could try and use shakawear imo,not many brands use them but theyre pretty good and can be cheap depending on where u get them
