My hall bathroom linen closet inside demension is 37 inches wide by 26 inches deep. It is very easy to access because the door is 30 inches wide. It has 5 shelves in it but could easily have 6. I think the size is more than adequate. We don't store sheets in it but it does hold a lot of things including a case of toilet paper and a case of paper towels, pool towels, bath towels, and all sorts of other assorted bathroom items. My MB closet is another story. It is a tunnel at 37 inches deep and 22 inches wide with a 16 inch door. Not sure what the previous owner (who was the builder) was thinking when he put that closet in. Maybe he had extra, extra long arms!

You have a good enough rough opening and may need it depending on how square your opening is .If the opening is square or close to it I would nail a 1X on each side and shim to make it square.Your casing will cover the gap at the top so no need to add.The 1X on each side will still allow 1/4" each side to shim the door jamb.

If the door to your closet can be centered in the 8' wall, you'll find reaching everything easier. You could build a couple of corner cabinets (for your accessories -- hats, purses, etc.) with 16" deep side walls (two 8" vertical boards on each side w/thick plywood triangle shaped horizontal shelves between them). You'd attach the fixtures (stainless steel is much stronger than the plastic ones) that would hold your rods to the sides of the vertical boards. At least on the wider wall, use two rods, one hung high enough so that shirts can be hung on it and not touch the floor. The higher rod should be above the lower rod the same distance as from the floor to the lower rod. You may need to support the longer rods in the middle with a hold drilled through a vertical 2"x4" board. On the shorter side walls, you could add a floor to ceiling row or two of shoe shelves beside the corner cabinet and then either a single high rod or double rods between those shelves and the wall to the bedroom. However. If your closet door is in the 6' end, you're likely going to find out very quickly that you can only hang clothes on one side of that and accommodate only 1' deep shelving on the other side and walking sideways between the shelving and hanging rods is awkward … and you're going to need a really good closet light because the light from the bedroom will not be enough. If you only have a few dresses requiring a single high hung rod, you might consider investing in a wardrobe so you can make all your walk-in closet rods double rods.

this one is 20" and prob a better size then the 12" or 26". in chrome https://www.luxedecor.com/product/crystorama-maria-theresa-mini-chandeliers-chandelier-cry4476_3540392?utm_term=2486491_3540392&q=123&utm_source=google&utm_medium=cpc&utm_campaign=1341198707&product_group=428958793864&campaign=1341198707&adpos=1o3&matchtype=&adtype=pla_with_promotion&kw=&gclid=Cj0KCQjwla7nBRDxARIsADll0kAW06cX62ECIF0BSIgFq0STDf9xv7ueGbLk1cNjtHDBRdGpwtNjw-8aAhGfEALw_wcB
