I have a lovely 3 month old baby but it's been a long road, various health issues and practically been housebound during pregnancy and post but starting to venture out and finally feeling myself again
Apart from one thing. I've gone from a fairly consistent size 12 to around a 16-18. I don't have anything to wear apart from my (very stretchy) maternity clothes, pyjamas or DH's t-shirts 
I used to take pride in my appearance and live clothes but looking online my confidence is shot and I've got no sense of what would fit me from the shops I normally go to...
I've decided I need to brave the shops, preferably one shop and buy a couple of versatile outfits to see me through. I'm breastfeeding which is why there is a time limit - that also has a little bit of sway on what I can wear.
Sorry what a lot of ramble to get to my question but I have some options shop wise I could go to and feeling a bit overwhelmed on where to try. I really don't want to spend too much since I'm hoping to lose weight soonish.
I could go to a retail park with a
Next
Matalan
Or go somewhere with
Zara (not sure they cater for 18 if I need it?)
New look
M&S
Or it would be a bit of hassle but I could get myself to a Pri-Mark
Any suggestions on outfits/styles would be so appreciated. I feel so lost.
