I need to buy the basics of a whole new wardrobe on £200 - please help me decide what I need!

[2point4kids]

I have just had Ds2 and nothing fits me. I am living in 'make do' £1.50 T shirts from Primark etc, that I hate.
For Christmas DH said I could have £200 to buy new clothes with whenever I was ready after having the baby.
Have made a date to go on a shopping trip for end of June when Ds will be 4 months old so should be pretty much where I will stay size wise.
I am a size 10/12, big boobs but the rest of me small framed and 5'3". I do also have a post baby saggy belly although normally I have a small waist so am hoping this will go down a bit by then!

I usually shop in high st places - I like Topshop, Oasis, DP etc
I just bought this dress as I saw it and loved it, but usually I prefer trousers to skirts.

Am open to suggestions!

I have the dress in grey and will be wearing with a wide red patent belt!

Not one to ask for fashion advice but good luck at losing all your weight 4 months after baby's birth. I can only dream.

Just have a fast metabolism I think!
After DS1 was down to size 8 after 4 months (smaller than I was before I got pg!)
Now DS2 is 10 weeks old and I am already down to size 10/12 so will probably be down to size 10 by the time he is 4 months I reckon.

I really like these shoes in red

but also love these ones in turquoise

Might have to base my summer wardrobe around one of these colours!

I have seen these jeans in the shop and like the look of them, but not sure that wide leg will suit my short little legs?

Am thinking linen trousers would be a good bet

Like white, but is it a good idea with 2 small messy boys to look after?
Maybe the brown then... would go with the turq or red shoes i think....

That dress is gorgeous! I will be ordering one.
It can be dressed up or down, very important!
