Confession, I have three Erins! Blue striped, multi striped and white. They’ve been brilliant for this transitional weather in May. They are boxy, so I would size down if you are narrow shouldered or petite of bust as the style might swamp you. I’m a standard size 16 and bought 16’s. Just the right amount a swing and gently body skimming. The material is exceptional as with all Ivy tees. Treat yourself!


Fit perfect, very comfortable, hope it washes well

The perfect tops

Honestly after buying a few breton tops from Ivy, i am converted and wouldn’t buy from anywhere else. Everything about them is spot on. The material, quality, fit and range of styles / colours is perfect. I bought my first Ivy top 2 years ago and it’s still going strong so worth every penny!


Love Ivy tees.. they are a bit pricey but honestly worth every penny. They're so soft, wash well, keep the shape, and go with literally everything.

A classic done well

The oversized cut is really flattering and chic, and the fabric is light but not at all see through, so I've managed to wear mine with a black bra underneath with no show through. It's washed really well. A classic that I find myself reaching for again and again.

we create everyday essentials

Our fits are designed to make sure women feel comfortable and confident whatever their lifestyle - we don't cut back on fabric to save a few pence and increase our margin, but instead will make sure we allow for great coverage in a flattering and forgiving way.

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.
