Firstly, you need to go to a lumberyard or building supply not the internet or a big box. If the current opening is 32.5” with drywall, the framing is 33.5”. This will fit a 30” door unit. You need a 30” bi hinge door unit to get this look, two 15” doors in one jamb. Easy for a lumberyard.

Thank you so much!

Have the door opening properly cased and trimmed with wood. Then have a ready-made door trimmed/cut down to fit, or have a custom door or pair-of-doors made. I would hire a recommended professional for the job....it will cost a bit more but will likely be done right and a lot faster than DIY. If you know a building or decorating contractor, h/s may have a good person to recommend.

I agree case the opening then get the doors BTW 2 doors in that space will always need to have both open for use.
