Luckily there's one picture of the "Adam Suite" as you called it, which was B51 (occupied by Charlotte Cardeza and her son). You can find the actual Titanic photo in various books. Its (and this is from memory) on pg. 57 of the Lynch/Marschall book, a small picture showing the fireplace. A much nicer and larger view can be found in Dave Bryceson, British newspapers book (sorry I can't recall the name), I think it's on pg. 16 there.
There's several pictures or illustrations of Olympic's Adams sitting room, although it didn't look exactly like Titanic's, it gives you a really good impression of what that style on Titanic would have looked like.
There are no surviving pictures of B53 or B55, but if one knows Olympic and Britannic well enough, you can figure out exactly what B53/55 looked like on Titanic.
The wardrobe chests would be unpacked and all the clothes would be placed into the dressers and or hung on the racks provided in the wardrobe rooms of the large suites which were similar to walk in closets while the smaller suites had average sized closets and or freestanding wardrobes.
