as the title says.
for example,if one was to marry ysolda, and have here move into your home,are you now able to change her clothing?

reason why im asking because id like my char to marry sylgja,but she wears mining clothes and thats a real put off, is it now possible? having youre spouse wear vampiric clothing from the dawngaurd dlc would look cool.

Only if your spouse has the follower option, can you change their inventory (I.E Janessa, Lydia). They will equip items better than their original only.

So that seems to be a "No"

Indeed

so it hasnt changed,thats a shame really,i like sygjia,and ysolda,they look more feminin, well it looks like im gonna have to try out another date one who likes to change thier clothes lol

A real shame considering giving your spouse a new outfit to wear around the house was one of the things featured in gamejam along with adoption. Ah well dress up your spouse is something that could be included in a future patch.

I was sure they'd include giving gifts to your spouse in Hearthfire...

You could try reverse pickpoceting... I'm on PC so if I wanna change an NPCs stuff I usually just console 'em!

reverse pickpocket doesnt work. it shows up in their bartering stuff. ysoldas like "want this chefs tunic?" im like "......no......"

Not too disappointed. I can see Aela telling me where to stick it if I give her a frock to wear.
