Buying from My Lolita Dress

[alice-seabrooke.livejournal.com]

So I decided to seriously treat myself if I pass all of my finals (especially physics), and I found an indie brand jsk that I love on My Lolita Dress (http://www.my-lolita-dress.com/), and they also have Classical Puppets' bell-shaped petticoats.
I was wondering if they were trustworthy/good quality?  I know they have brand stuff, but I also know that doesn't really mean anything.
And hints about their sizing are totally welcome. (Especially because the jsk I'm looking at has bust measurements that are significantally smaller than the waist, or maybe they're just reversed.) (http://www.my-lolita-dress.com/gothic-vintage-lolita-jumper-dress-with-thorn-flower-yuan-61)
