Would dolls clothes sell online?  

It is quite probable. Have you heard of reborn dolls? These are very life-like dolls that people can spend a fortune on. They are very expensive and some owners spend a lot on outfits so if you were doing individual hand knits that might be a good market to aim for.

Definitely. If they looked good. By that I mean, old fashioned-looking doll clothes would sell better to older women. My grandmother collects dolls and im sure she would purchase them online

Nowadays dolls like dollfies or pullips have grown pretty popular, and owners usually have more than one.
Some of them know how to make their doll's clothes, but some others don't, and they usually look online clothes to purchase for their dolls, so I think you'd be able to sell them.

It could be possible. There are alot of sites you can try to sell on.

Ebay, I like craiglist and walmart has free classifieds now also to post on.

So dose the newspaper in your area.

Also the pennysaver. Good luck to you.

I think they would if you can find the right marketing outlet. As someone else said, craigslist would be good. I'm not sure about retail outlets, but etsy.com or ebay.

You might sell more after Christmas, when new dolls have been received for Christmas and people want more clothes for them.

I think they would. I have come across some adorable clothes for dolls on Etsy.com and I could see them being purchased as gifts for young girls. (I couldn't tell you for sure-I have 2 boys....but if I had a young girl that played with dolls, I would buy some of the clothes!)
I think handmade is a big draw these days, and in this economy, people seem willing to spend money on something that is crafted better than what some of the "box stores" tend to sell.
