Asda is something like £12 a pair of jeans which I thought was pretty good and I got a couple of t shirts from H&M in a 2 for £8 deal. I also found a couple of nicer tops for going out from H&M for about £15. I bought a few t shirts from primark for about £3 each and wore them with a nice normal cardigan
Did you not fancy the ASOS stuff? I’ve lived in their dresses for 2 pregnancies. I bought jeans from Jessica simpson’s label in the US (which isn’t super helpful I know) and a bunch of plain black maternity tees from ASOS accessorised with various scarves. But mostly in ASOS dresses and leggings from next.
I'm 16 weeks and have a bump. I'm just wearing usual leggings, a size up in black jeggings. Lots of long tops or dresses, particularly ones that tie at the back and tights. Not a big fan of maternity wear. Stretchy jersey dresses work well as you get bigger.
I got most of mine second hand off ebay as I wanted over bump jeans and most shops had under. Asda have quite a cheep range. Tbh I have mostly brought primark tops in big sizes and asda tops in a big size. And got some black trackies off sports direct
