I saw the same tshirt on 2 different women in Norwich today and wish I’d asked one of them where it was from. It was a navy base with lots of small, brightly-coloured flowers on. Short sleeved rather than capped sleeve. I’m thinking as I saw two women wearing it it was maybe somewhere affordable like Primark/Tesco etc. I’ve checked on Joules, Next and Sainsbury’s but can’t see it. Hopefully this is ringing bells with someone!
