There are plenty more.
And it makes sense....Risen Road isn't exactly fashion central of the Sword Coast. Druids would have no use for fancy clothes, or really any other clothes that aren't....druid-ish.
Goblins even less.
The rest of Act 1 are ruins more or less, no place that would really have decent, intact clothes.
Act 2 is pretty much the same, apart from maybe the 2 places that aren't ruined, and then again, it's a bit of a stretch to say those have plenty of intact clothing options....
Only confusing thing about Act 2 is that Robes of the Absolute are a clothing item, but Selunite Robes are Light Armor....not sure why...
Naturally it wouldn't make sense to have fashionable panties and dresses in the Grove, but it doesn't have to since a lot of gameplay aspects in the game do not make a lot of sense, so it still sucks having just 3 types of different rags in ACT 1. There's literally just 3 rags available throughout its entirety, meanwhile all companions have these super duper clothes and underwear from the very start.
Which is why I end up stealing underwear from other companions, because I deserve to look fancy too. Right now my Gale is at the camp in his undies only due to lack of underwear options
