I would say something somewhat simple since you want to use it both and one is more Classic while the other is more Sweet. Maybe something brown since there is brown in the Bodyline skirt and it’s a fairly versatile color for Classic that I think could work with that dress since it has that ivory background that looks nice with brown. Something like this, this, or this in brown might be a good option. You could also technically use red, but I think it would be better to use a wine red for the Magic Tea Party dress and a regular red with the Bodyline skirt so it maybe hard to get just the right color to be perfect with both. If you did want red though I would lean more toward the wine red.
I would say purple tights and green shoes would work well. I’m not sure what you mean by gem colored. I would say to use mint though. I would definitely say you should have a blouse or bolero, and I think this is one of the cases where you could use a cutsew under a JSK as long as you were using the one that was made specifically for that set. The Alice Candy cutsew is adorable and it looks like this if you put it under the JSK.
You could use a lot of different styles of blouses though. Something Sweet in lavender or mint or white. There are really a lot of options. Then you could do a cute chiffon lavender or mint bow or otherwise fluffy hair accessory. There are some really cute ones on etsy and storenvy.
Gosh this didn’t sound hard at first but then I really too notice of the “no lace” part and that made it much harder to get something with all of the other elements because especially with Sweet Lolita no print is often compensated for with pretty lace and other details. I did find a few things though. The first thing I thought you might like is this JSK. It’s shown with a polkadot fabric but for an extra $5 and a little extra time you can have it made in plain black or blue fabric. With shipping and that extra charge for the custom fabric it’ll be a little over your $60 but not a lot and it does have everything else except for the detachable bows. There are also a few things from this shop you might be interested in. They’re mostly a little more than you were looking to pay but they look like very nice quality. They also mostly look more Gothic or Classic but there are a few items that you could definitely use for Sweet with the right coord, like this skirt for example.
Those are really the only things can think of that meet most of what you’re looking for. Everything else I can think of is not at all Sweet or has a print or lace or doesn’t come in the right colors or it’s brand. There are a lot of things that come to mind that would have been perfect but they’re not available anymore and there were even a few shops that I thought would have something perfect and then I go to them and find out they’re closed. If I do run into anything else though I’ll edit this.
I think it would most likely have to be a mix of Sweet and Classic, but you could definitely put Classic elements into a coord with it. An elegant white high-collar blouse, sax shoes that are somewhere in between the styles, white legwear with maybe a touch of sax to it if you wanted, a bonnet for a more elaborate look, a corsage for something more simple.
All this queen stuff is getting out of hand.
But anyway, I think it would work well for a Classic/Sweet coord because it has a very Sweet look in the details but the sort of grayish purple is more Classic. (The stock photo isn’t great for showing the coloring so I had to look for a review to see the color better and I actually kind of love it. It’s apparently the same purple they used for Love Nadia.)
You could use a number of different blouse styles, but I would love to see it with a high collar. It think it would give it a very elegant look and it woudn’t take away from the pretty yoke. A square neckline may also be a good option so you get the sleeves and the shoulder coverage but once again nothing covering the top of the JSK. Most styles of collars would work fine though, I would just stay away from anything that has a big bow or anything like that which would hang down the front.
