If you had £100 to spend in M&S...

[Marshpillow]

I have £100 to spend in M&S, and no idea what to spend it on. I'm generally quite rubbish at clothes shopping and haven't bought any new clothes in maybe a year. Please could someone recommend some nice things?
I'm in my late 20's, currently size 16 but hoping to lose a bit of weight, 6 weeks post partum so would like to disguise horrible wobbly tummy. SAHP so don't need work clothes.
Thank you in advance!

A cashmere jumper in either black or grey. And Prosecco. Maybe a scarf too.

This and I'd size up so it was slouchy.

Casual trousers A bargain. I have them and really like them.

I love that jumper Remus. I wish you hadn't posted it as I am soooo tempted :)

Cheese and their dupe perfumes

I did a few years back and blew the lot on underwear!

Food. Their clothes are no longer amazing. I would rather spend the money on a seasalt or jigsaw or white stuff outfit than Mand S. But their food... amazing stuff.

If you need any make-up the M&S Rosie Huntingdon-Whitely range is really decent quality.

A cashmere jumper and spend the change in the food hall.

A Rosie dressing gown and Pjs

Their handbags at the £79 price point are really worth a look. Some great designs and good quality that you'd normally pay loads more for.

Bras and pyjamas, the clothes aren't worth much of a look in I reckon.

This dressing gown, a couple of bottles of their fizzy pinot blush and the rest on Percy Pigs.

I have that dressing-gown rum - it's my favourite item of clothing

I can't get excited about their food, especially now they've stopped doing the one thing I used to go there for especially (leek and Gruyere tarts, in case anyone's wondering).

Their dressing gowns are nice - lovely and fluffy.

Thank you all for your help! Going to have a proper look online now at your suggestions
