>>8649443>>8649554pointed collars are used in gothic so I wouldn't say there's something inherently wrong with the blouse itself, but I agree in that it doesn't really fit well with the elements of this coord.
the design on the skirt comes across as less strictly gothic and more of a hime, ott classic kind of thing. the blouse seems like it would suit, say, one of moitie's gate pieces or maybe something from boz. for this, I think you should pick a blouse that's a little more flowy and princessy. I also feel the crosses on the collar of the blouse just don't really fit with the print. if it were gold roses or swans or something then maybe, but the print is a castle, not a church.
if you wanted to go gothic with this, that's also fine, but again I would go with a blouse that's more elegant and less "industrial". there's tons of different themes in gothic but the theme of the blouse just doesn't go with the theme you'd want to go for in the skirt. I also agree that you should get rid of the tights; I remember having a pair when I was younger and they just look too costume-y, like something cheap from the halloween store. lace tights, textured stockings like the other anon mentioned, or something black with elegant gold details on it. as for accessories, depends on if you want to go more gothic or hime with this but lace wristcuffs if you use a shorter sleeved blouse, pearl or gold bracelets, jewelry with swans, roses, etc. I would definitely use the rose theme that's happening in the print. for example, maybe a red bonnet instead and with some rose clips in the front. (red bow is fine but if that cross thing isn't removable just find another one) likewise maybe a fake wrist corsage, or a silk rose pinned to your blouse, etc.
