They are running a bit short on long-sleeved white blouses aren’t they? Out of what is still available, I do like this one but I don’t think the ruffles would look good with a JSK. Your best long-sleeved option may be this. I know some people aren’t fans of the look of a fully shirred blouse, but because you’ll be wearing it with a JSK it won’t be at all noticeable and it might actually be a good idea because the sleeves are detachable so you could wear it other times of the year.
I would say 075 in white. I would say 373 but white is sold out and I think that’s the color that would work best. I never recommend 009 to anyone unless they’re wearing it with something rabbit themed.
I think it’s decent. You’re right, the skirt is a bit busy but I don’t think it’s too bad. I would however just recommend plain black tights rather than anything with a pattern. I was a bit iffy about the skirt at first because it looks pretty bad on the model but it looks better on the mannequin. I think they just used a really bad petticoat for the model (probably one of their own and it may have been on it’s last legs from being used for several photos) not to mention the way she’s holding out which just looks stupid because she’s pulling it out farther than it naturally should go.
Anyway, I was going to say that if you don’t like the blouse you should get a different blouse, but I understand that if you’re just getting it as an idea to see if you like Lolita or not you probably wouldn’t want to go through the hassle of getting a custom blouse unless you absolutely could not find anything that fits otherwise.
I actually have that blouse. Because it’s fully shirred I prefer to wear it under things because I’m not a fan of the look of fully shirred blouses, but overall I like it a lot.
