Well depending on your defense level is what you will be able to wear. For training its best to wear torags if you have the appropriate level to wear it because last time I knew it has the highest defense of all armor.
Since it sounds like you've never been a member before, think about being able to wear a neiznot helmet as well (Quest required). Also do the whole quest RFD in order to get barrows gloves.
So your outfit would be: Neit helm, glory ammy, torag chest, torage legs, whip/dragon scimitar, rune kite sheild or rune defender, dragon boots, barrows gloves and Ring of Wealth. 15m Will buy you all this easily.
