There is plenty of things gouing on there:
But this is what I see

a one colour background or a background with a slight gradient (bright red to dark red for eaxmaple)
so either a solid colour adjustment layer or a gradient adjustment layer will be your first layer.
Then build upon it with various shapes (circles, stars, stripes), they can be shape-like brushes, or just something you draw directly with the brush tool on a transparent new layer above the background layer. There is likely to be at least 2 different layers containing different kind of shapes (1 layer per different shape). These new layers will be filled with shapes in a different colour than the background and their blending mode set to overlay or screen (depending the colour used), and their opacity lowered to something like 50%. It will give this effect of shapes interacting/overlaying each others.

Then you can add a vignette by add a new level or curves adjustment layer, make the whole image darker,and mask the center with a very soft brush, to hide the center, thus darkening only the edges.
see how it looks here:

I am sure there will be some refinement (blur the shapes a little?) but the general idea is this>

I have done the circles and flowers with the "fx brushes" from Kyle webster's packs, some of them are available within Photoshop, some of them you'll have to download:
hit the F5 to open the brushes panel and click on the hamberger menu, choose "get more brushes"

for help using the adjutsment layers, try that:

Of course, like everything in Photoshop, there is more than one way to do things, but this one works 🙂
