I think brown or navy would work really well with the wine and off-white is versatile enough for both. If you like a darker look you could also do black.
I think the purple is dark enough that black would work perfectly.
The circle lenses I’ve had have been from Honey Color. They carry a variety of brands and styles and it’s very easy to find reviews for most of the specific brands they have if you want more information on what you’re buying.
The lace isn’t the best but it’s also not the worst and since it’s the same color as the blouses and doesn’t stand out it’s fine. And I think with the right coord 1312 could work fine with Gothic.
If you’re looking for boots, something with a more Victorian feel is great like these for example:
Oxford heels are also popular:
Then there are shoes that have a very Lolita look in general with bows and ankle straps but are more elegant and mature for Classic Lolita:
There are definitely more options out there though. Always remember that if you have a question like this you can look through my tags. The inspiration tag is where all of the pictures I reblog will go but more specifically I would take a look at the shoes you see in the Classic Lolita tag.
As far as head accessories go I can really see it with a fancy hat. You could do something with a lot of flowers to play off the floral lace, something with some lace and dripping pearls like the dress, or something similar but a tiny bit simpler. There are other styles of headwear you can do too like round headdresses, fuller headdresses, and more simple floral arrangements.
They’re a little taller and a lighter brown, but Payless has these similar oxfords.
Oh I think it’s gorgeous. The lace is phenomenal, the details are beautiful, I really adore it in every color.
Great! If anon (or anyone else for that matter) is interested, you know who to talk to!
"Ball" shaped would be a typo.
