Yes, from Primark of all places (who knew Primark had a website...interesting), I think that Primark are really exceeding customers' expectations when it comes to their range of underwear, loungewear and nightwear. I popped into my local Primark on a Sunday afternoon and when I say 'popped in' what I really mean is I spent an hour in just the underwear section right at the back of the store because there was so much to look at. I really like the layout of this section, it's spacious and you can see just how many options there are to choose from; sometimes the sizes are all muddled together but that doesn't happen as much in this section as it does in others around the store.
Primark do an extensive range of bra's from maximise (solid padding), to push-up (less padding), t-shirt, non-wired and bralets just to name a few. The best bra fitting tip I have found is from an episode of This Morning, which suggests to go for a smaller back size (which is a must for Primark bra's because they will stretch and feel looser after a few washes) and then go for a larger cup size and this should give you a good, comfortable fit. I also opt for thicker straps and band because it feels more comfortable and supportive and doesn't dig in or cause back rolls which is a pain in the arse under a tight top or dress.
