OP for autumn

This feels like the year. Since I first started wearing lolita way back I'v wanted a longsleeved OP with a high neck. I'v made several of them myself but since I'm quite a poor seamstress it doesnt count. Along with all the other stuff I'm constantly looking for on auctions, this year I'll be browsing for something along the lines of this, from favourite brand Baby, the stars shine bright Or this dream dress from Mary Magdalene, I am curious to weather it would fit me or not, I have heard that they are really tine unfortunaly ;A; With thick black stockings, high heels and my black half-bonnet, it won't only look dangerously fabulous, It will also be quite warm.
