Opinons wanted please on this dress

[flipflopper]

to wear with jeans

Also not sure whether to get 12 or a 14 as I am sort of in between sizes

I think jeans may look a little bulky underneath that - much nicer with boots and opague tights imo. Oasis dresses are quite generously cut (unlike their trousers), so I'd go with the 12.

You might be right but it looks a bit short to go with tights.
Do the sleeves look puffy? I hate baggy sleeves

I think they do look a little puffy, yes. This is it in grey on the Oasis website, I would definitely describe those sleeves as puffy.

in grey

Leggings or tights IMO. Deffo not jeans.

Also would look nice with a belt over it.

is this one better?

That would go with jeans a little better. Bloody hell, is that a dress? I am getting old.

I wouldnt call it a dress either, and definitley wouldnt wear it as a dress!
