You really you're beautiful, but you need to ditch the cat ears, honestly, they don't fit in with lolita fashion at all, I know I've read and you say they don't leave. But as someone else has suggested, maybe theme the outfit around cats then, not something from a Halloween or drug store? And get higher quality, cuter cat ears then? I mean if you're really that hard pressed to keep them, but they are very much deeply frowned upon in this style. You really just won't be taken seriously wearing them otherwise and I'm afraid people might be quite rude to you about them.
Also I'd suggest ((I'm sorry)) finding a different dress. You don't need to spend hundreds on brand, but somewhere a little more high quality, Bodyline is pretty good I'd say I've used them before.

Also, I'd say the moon necklace doesn't really fit it in well with lolita fashion, it's a little plain and you definitely need to invest in a peticoat, this place is pretty good,
https://www.etsy.com/shop/IntheStarlite and they're more than decently priced I've had a peti from them for about five years and it still holds shape nicely and perhaps... you could work with the socks/tights with the right outfit but something a little less halloween-y I'd say.
I don't mean to be so harsh and I'm sorry if I come across as rude to you, I'm just trying to help you out a little bit.
