What to pack for a spa break?

[Quanked]

2 night break
Sightseeing on the first day
dinner in a pub the first night
spa day on the second day
3 course restaurant meal on second night
spa in the morning of third day, then a walk and lunch before heading home.

I’ve lived in DMs, jeans, thermals and a jumper all winter so struggling to think of clothes outside of that

If Jeans and jumper is what you are comfortable with why not stick to the look but swap the jumper for a nice cardigan and maybe take some fancier tops.

Jeans, jumper etc fine for sightseeing, pub dinner, walk and lunch. I'd travel in that with a nice pair of boots and pack trainers for walking then included address for restaurant dinner which goes with the boots

Oh and if swimming makes sure to pack at least 2 swimsuits.

Thank you
so
Wear jeans etc
pack dress, 2x swimwear, change of underwear, change of top etc

What kind of dress do people wear these days?! I’m only 5’2 and a small build so can’t wear anything too voluminous
