Spoiler alert: I got it wrong.
So if you live in the UK you will know that recently the weather cannot make up its mind! It's really hard to know what to wear! So I thought I would throw on this dress from Marks and Spencer's (but bought for £2.25 in age UK) and this denim jacket which is also from Marks and Spencer's (but bought for £3.50 from the Samaritans). I ended up miserable and roasting because even when I took the jacket off the dress is very decieving and holds heat really well!! I'll be putting this away for winter I think!!
