"Proud Poppy's service is second to none! No question is too much of a challenge! This winter it's ALL about chocolate brown and light blue, and this Billi Tank is the perfect item to be worn with any combo of the blue/brown range! It's comfortable to wear, it doesn't ride up and the fabric feels amazing!"
"This tank wont let you down, feels so stretchy and soft, colour is unique - not many tanks available in this cute denim-y blue. Sits beautifully everywhere and length is perfect at 171cm tall."
"Great fit with the perfect length for a shorty like me Fabric is soft and comfy and it’s so good to get a great range of colours 👍👍👍"
"I am not saying I have 12 different colour ways of these but I am! They just go with everything - under a Tammin shirt, paired with a Carrie skirt or take you pick with the Larsa or Gina pant. Your options are endless. These are true to size. I am 174cm tall with an apron belly normally in a size 20."
"So I’ve seen people post about the Billi Tanks and the team rave about them but honestly, in my head - it’s a tank top…. How can that be that amazing! Well, in the sales I grabbed one (because why not) and well aren’t I mad I didn’t grab more! It’s the darn comfiest tank I’ve ever put on my body and now I understand why people have raved about them! Do yourself a favour and get one… get them ALL!"
"The straps, shape and feel of the Billi tank is so good! It’s so hard to find a good staple tank, and this hits the mark."
"Love it! Such a comfortable tank, wish I had bought it sooner"
"The Billi tanks are so stretchy and comfortable - love them for work and also have some as sleep singlets for warmer nights 💕"
"So comfortable and they look great too! I will be buying more! Love the colours!!!! Fast shipping makes it even sweeter!!!"
"I love these tanks. So comfortable to wear & such a good staple for mixing & matching different outfits."
