A similar set of armor can be tailor crafted at Tier 6 for the most expensive bundle (Also these items can be found on the auction house often). However the cloak I believe is store only. (I might be mistaken) In my humble cosmetic opinion I would not suggest purchasing the most expensive bundle unless you're low on game gold or have no crafting abilities. If you do have crafts/gold, but not the level/armor requirement, I would instead suggest purchasing 10 slots in the wardrobe for 495 TP.
As for the second highest bundle a few of those items are Isengard instance drops, so if you aren't high enough level to do Isen I would snag these! (Unless of course you do have the wardrobe!) Even if you do have the wardrobe, the bottom of this outfit is extremely hard to find on the auction house, at least on Imladris server.
The bundle for 350 is an extremely good deal! The items separately in the store are 195 for the dress, 195 for the cloak, and 150 for the circlet. So altogether that is 540TP, you save 190TP!
Last but not least, or actually it is the least! The last bundle is for 325. You cannot beat that price! You get a cool little pirate costume that will be good for Halloween!
