I recently bought a fleece but want to return it even though i've worn it a few times...?

2 weeks ago I bought a fleece from J. Crew. I've worn it a number of times since then but I have kept the price tag on it. Now the fleece is on sale for $20 cheaper and I want to return it and rebuy it at a discount. However, the fleece is a little loose considering I've been wearing it. Also, the store only honors price change adjustments within 7 days of purchase, and mine has been 14 days. Is there any way I can dry clean the fleece so that it looks brand new, considering I have the tag on? And then I can return and rebuy it? Does dry cleaning make it look good as new? Another alternative is that I go and ask for a price adjustment even though the limit is 14 days. What should I do?
