You have this, you're not a lolita, but you want to use it in a raffle as a prize people can draw, as a loophole to...? something, not clear.
To answer, that item is not a coveted piece, and would seem like a 'I don't want it so I have to give it away to get rid of it' sort of gift, which is still nice but won't be well received, except by new folks that wouldn't possibly be affronted.
Building a wardrobe takes time and consideration, curating, but littler items like accessories, bags or jewelry can also be costly and hard to find, plus a lot of lolitas are paycheck to paycheck from what I can tell, not so much of a budget for smaller needed things over main pieces.
If you have a budget big enough to use a main piece from AATP, you could just as easily get several smaller/pricey for what it is items to the same value.
Or, just get the dress for you and don't do a raffle?
