Reviews
You just cannot go wrong with a Billi Tank!
"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!"
Soft, stretchy, cute colours - recommend 100%
"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."
Ticks all the boxes
"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 👍👍👍"
A full dozen
"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."
Why did I wait so long
"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!"
"Great top and colour! Great fit too"
The straps, shape and feel
"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."
