I don`t have enough information to make even a guess at the possibility of success. There are several examples of successful consignment retail shops. In your case, because of a low price per item - you may have a challenge keeping track. In the category of used clothes, you would be "competing" with Goodwill and other donation stores. I would suggest doing some basic financial projections to see how they look.

Yep, me too Nikole!
Regan123, since you are new to the retail game and you already know the niche you`re after, would it be better for you maybe look into an already successful franchise that fills that niche? Something like www.ouac.com might be worth looking into. That`s where I shop. Just a thought.
I really think that success depends a lot on location. I have seen a lot of these shops come and go in our area. But, on the other hand, two shops have remained for many years. So my advice would be to do intensive market research to find the best spot for something like that.
Just some laymans advice from someone who knows nothing about that kind of business.
