Will an Abercrombie extra small hoodie fit me?

I just bought a hoodie online, the only size left was an extra small and it was a good deal so I just went ahead and purchased it. But I was wondering if it will fit me tight. Normally I am an extra small in shirts and hoodies in other stores as I am starting to realize now. I measured my own bust and it came out to be about 30. Yeah I'm small. I've had Aeropostale hoodies that were a small, but they were slightly big on me and I hate baggy clothes now. Last year I bought a hoodie from Target, an extra small which fit snug but the small was too baggy for me. I am about 5'2" and weigh 95 lbs. So far I've read all over the internet that Abercrombie is meant to fit snug and is great for petite girls. I've never shopped at Abercrombie before but I thought I'd start out with a hoodie. Please no rude comments please, I am not trying to fit in with the crowd or anything by shopping at a name brand store. Suddenly I just really liked everything I saw online that I never cared for before. I'd go to the store myself and just try a hoodie on if I could but the mall is too far. I'd actually love some feedback on shirts and tank tops as well, not just hoodies. Thanks.
