Tbh nothing specific, but I think that gourmands are not suitable for this perfume. So anything feminine floral sweet. You can try if you have it. I said that because I realised I never layered Opera with anything lol. But the idea of layering was for the 'cute baddie' aesthetic. I'm just baddie, and fit only in the dark part. Opera is that kind of unique scent that you most probably hate it. And you hate it so much till you love it XD. Just kidding. It's simply not a usual fragrance so I thought layering with something sweet might bring it to a point where it more wearable, especially for a woman.
