Help please! Outfit for girls day out & evening drinks

[hotsweetpotato]

As title!!
Going on a girls (30-40 yr olds) day out,
Walking round shops & touristy stuff in city, then meal & drinks in evening.
Weather still looking good so I'm lost at what to wear......
Any ideas?!?!

No opportunity to change in between?
It depends what you mean by good weather. If pleasant rather than hot, I'd go for 7/8 jeans, lightweight top that was a step up from a tshirt (IYKWIM) and nice espadrilles/low wedges/flat sandal type shoes. If actually very warm/hot, a dress rather than the jeans and top, and the same shoes. One of the denim/chambray types there have been a lot of this season.

Thanks,
No, no opportunity to change & don't fancy carrying lots of extra clothes with me..
Was thinking maxi dress or dark green skinnies with silky vest top & flat sandals,
May consider carrying wedges round for evening.....
Size 8/10 (slight mum tum) 5'4 ish...
