I've done this a bit to get some good gear. However it works best when you've got 100 skill in alchemy, enchanting and smithing plus all relevant perks.
There is apparantely an exploit possible, whereby you enchant some fortify alchemy and enchanting clothes, equip them and make a fortify alchemy and fortify enchanting potion, drink those while wearing fortify enchantment, then repeat the whole cycle again and again, thereby fortifying your alchemy and enchanting via clothes and potions by higher and higher levels.
And once you're done you then make a fortify smithing potion and fortify smithing clothes, then go and smith your items using your over-the-top fortify items to make extreme armours and weapons. And then of course you improve them and enchant them to high levels too.
I've heard of that exploit before.
Decided to start a new character after wanting to make some different choices, currently at level 4 heres my loadout:
Imperial Male
Full steel armor, steel shield and steel war axe
I want to improve my smithing and go through the armor perks, selling off each set once my ability outgrows its worth. I also want to work on my alchemy skill much more, having not valued that so much in previous playthroughs and as a result am often left short of potions. Same with enchanting.
I also want to make an increase in my blocking skill as I painfully undervalued that, attempting to brute force my way through battles often being horribly wounded or killed. I havent died yet while using the shield, and have lost very little health due to its coverage and the war axe's damage value.
