I think you are off to a great start, and that if you fix the issue you noticed (lighting in pics) then you will be golden.
I had almost this exact same problem with the first batch of pictures I took. My products are a bit different, but what I did was I took my pics outside.
On a semi cloudy day with no direct sunlight on the actual item, there don't seem to be any harsh shadows or glare, and it costs basically nothing.
Even if you do decide to get some equipment I would suggest trying outside.
Also, as someone else commented earlier, having things that are wearable actually being worn by a person in the picture is a really good idea.
Hopefully that helps, good luck!
