Another fabulous tee from Ivy

The Thia Tee is just what I was looking for. I’m a size 12 and the 12 in this style gives me the oversized boyfriend tee look I was hoping for. With perfect upper arm and bottom coverage but still cool and lightweight for the summer. Like all my other Ivy tees it is super soft, comfortable and washes really well.

Totally in love with my new Thia top. I love the shape and the soft feel fabric. Since receiving my order a week ago I’ve worn 3 or 4 times with different outfits and feel great each time. My Audrey top I bought in a 12 but sized down to a 10 for Thia and it’s still a loose fit which I like. Can’t wait to order another colour way!

These are the best T-shirts I’ve ever found! I’d become so fed up with buying t-shirts every single summer only to find by the end of the season they’d shrunk, shortened, pilled, seams had come down, or quite simply weren’t a flattering fit in the first place. So I was back to square one needing to replace them all. Not so with Ivy! These are seriously high quality, durable and uniquely flattering I think. I also adore how much sizing info is provided on the Ivy website - I have 6 Ivys now,, and I’ve always been able to choose exactly the right size and fit first time. No returns necessary. Absolutely love them!

Loved the two tops I bought will be great in the warmer weather, excellent.

FINALLY a fantastic basic

I’ve now got 2 Thia tops, thrilled with them is an understatement. They fit beautifully, bought my usual size (12) and it has the relaxed fit I love and is the perfect length (I’m 5”4). They wash brilliantly too and I can already tell are going to last. This is absolutely going to be my “go to” for staples/basics that honestly feel far much more than that. Thank you!

For every woman, every day

I created this range of t-shirts because I needed them. Before Ivy there was a big t-shirt shaped hole in my wardrobe that is now nicely filled with soft, comfortable goodness that I literally turn to and rely on every single day.
