New things that I've bought for my "maternity wardrobe":
2 x black work trousers from New Look maternity (under the bump)
3 x work type tops from New Look maternity, various colours
2 x maternity leggings (one black, one navy), New Look
2 x jumper dresses (knee length sweaters), Sainsbury's, not maternity range, size bigger than I would usually wear (wear these with the leggings)
2 x maternity jeans (one black jeans under the bump, one blue jeans up over the bump), New Look
4 x casual maternity t-shirts from New a Look (eg black and white stripes, grey with lacy collar etc)
2 x Tesco nighties two sizes bigger than I usually wear, not maternity range
1 x "dressy" top from mothercare maternity
1 x casual dress from mothercare maternity
2 x casual dress from New Look maternity (one navy and white stripes, one flowery pattern)
2 pack of breastfeeding vest tops from mothercare maternity
2 x maternity bras from mothercare
2 x maternity bras from primark
Then I still wear baggy pyjama bottoms, baggy tracksuit bottoms, longer/baggier tops, cardigans (particularly long ones), blazer/leather jacket type jackets, longish parka type coat from before.
Am 38 weeks tomorrow, been wearing maternity stuff since around 18 weeks. Reckon I will carry on wearing most if not all of the stuff for a good few months post partum too.
So as you can see New Look has been my go-to-place really! I have one very local though so that explains it. Got a few of the things from there in sales too e.g. the two black work trousers were reduced to £5 each (that's why I got two, to rotate!)
