Look for some sort of fashion convention, hopefully there’s one near you, where you can go up & down the aisles & see what you like.
Or, better yet, you’ll see things which you think you’ll be able to sell, as opposed to buying only what you personally prefer.
Conventions are a great place to hunt for good wholesale discounts. Lots of business can be taken care of, on the fly, too.
You can meet new friends, it can be fun and you can accomplish so much in a day, you won’t believe it.
Good luck to you!
