I actually hoped I might "run into" them during the Battle of Solitude...
"Jarl Ulfric, I... I regret to report that I may have accidentally killed some civilians."
"WHAT? I gave strict orders that no civilians were to be harmed. Did you not-"
"Yes but you know those two Altmer-"
"-understand what I meant when I said no-"
"-ladies from the dress shop near the city gates-"
"-civili... wait, what? You mean those Radiant Raiment women? Well... they totally had it coming. Carry on, Dragonborn."
That is too funny! I would really like to see that played out, as well! The Radient Raiment Altmers are kinda like Bethesda's mockery of today's Fashion Industry. Who here has not gone into a "Fashionista" store wearing "Street Clothes", only get snubbed while in the store. I think that at times the whole Fashion Industry is full of Narcissitic snobs. They all seem to have the "Emperor's New Clothes" syndrome.
However, if you are a Mage looking for stock clothing for self enchantments. That is the place to purchase the clothes you need for those enchantments. That is assuming that you are not looking to enchant light or heavy armor instead. They do sell alot of clothes. And if you ever need to pull off a "Bedlam" job in Solitude, that is my favorite store to rob.
