Shipping from Baby? Soooolved

I've ordered something from Baby online, and since I've only ever bought from the actual store, I'm really nervous waiting for it. How long does it typically take to get here in the US? Like, not just in the country, actually on my doorstep. C: I've heard the tracking numbers can take a few days to start up, and even then aren't updated all the time, so
it's pretty useless so far. D|
It's just a blouse, not even an expensive one, so would it get caught by customs? D:

Edit:  I got it now, I checked the number using the Japanese site, and it has all of the information. <3 It's in San Francisco, so it might be here tomorrow. Yaaaaay~
