This achievement can be obtained at Riverwood.
When escaping from Helgen you will pass through a Imperial torture room, there will be three cages, and a bag on a desk with several lockpicks. Lockpic the centre cage and search the body to collect his enchanted robe and hood.
When you arrive at Riverwood you will pass a Smithery where you can
do an unmarked/miscellaneous quest activated by Alvor, doing so will net you with smithing an item.
Walk straight along the road in Riverwood and enter the Sleeping
Giant Inn, and buy some ingredients from Orgnar, the man behind the bar, and use the table to his left to make a potion.
Now for the final part, travel south-west of Riverwood to Anise's Cabin and enter the cellar to find the Arcane Enchanter, now break down the enchanted clothing found in Helgen and use that, and a soul gem, to craft your own enchanted clothing.
Simple, it takes less than 10 minutes after leaving Helgen.
