NO NO NO to baby clothing online
I know from experience that it does not sell well at all. I still have stuff sitting here and boutique brands like Baby Lulu. People don't like buying baby stuff online, takes away from the whole experience of buying for the baby.
Now if you were to sell used clothing in large lots and certain brands only then they do better.
All I can say is research it very well. I even belong to Boutique Bargains - they basically tell you what to buy and when to sell it, they do all the homework for you but even with this I'm still stuck with a couple thousand dollars worth of inventory that has been sitting here for a good 2 years now
