If your boutique sells clothing, you will need to hang them up. There are hundreds of choices and types, so I’ve picked the ones I like the most.
Velvet hangers are thin, but weaker. If space is your main consideration these are the best. If you stock baby/toddler/small kid items, there are smaller versions available too. These are weaker, so don’t be surprised when they break over time or if you even get a broken one right out of the box.
Wooden hangers look nice, but take up a lot of space. I would only use these for very heavy and higher end pieces.
Skirt hangers are self explanatory. They are made of cheap plastic so their life may only be 1-2 years depending on how fast you rotate inventory.
Leggings hangers are a nice way to display leggings without taking up too much space. These are very small and may not fit on custom sized clothing racks.
