The Overshirt That Makes Everyday Outfits Effortless

Many layers feel fussy, lose their shape, or overwhelm your outfit the moment you start your day. This relaxed overshirt balances a playful pattern with an easy, flowing shape so you can stop worrying and simply get dressed. It moves with you from coffee to commutes to dinner, pairing seamlessly with light trousers in warm months and extra layers when it’s cooler. You’ll feel confident, put together, and ready for day-to-day plans without tugging or second-guessing.

What Makes This A Reliable Choice For Everyday Confidence?

• Playful Dots With Clean Balance: Add character without overpowering your outfit, so prints feel sophisticated for work, weekends, and travel.
• High-Low Hem That Works With You: Opens the front for ease and adds back coverage, draping smoothly when you sit, move, or layer.
• Collar With Shape Options: Wear it closed for polish or open for ease; the neckline frames your face and stays neat through busy days.
• Roomy Sleeves You Can Style: Fold the cuffs to show bracelets or keep them long for a relaxed line—without bunching or getting in the way.
• Season-Spanning Layer You'll Reach For: Effortless to pair with your staples, it becomes the piece you grab when you want quick, confident outfits with minimal thought.

I ordered my usual size but unfortunately it was a little too small, so I contacted customer service about exchanging it. The exchange was really straightforward and the replacement fits perfectly. I’m so pleased I gave it another try because I absolutely love the dress.

I’ll be honest, I was a little unsure about ordering as I’ve had mixed experiences buying clothes online. I wasn’t expecting too much, but I was genuinely surprised when it arrived. The material feels lovely and the quality is much better than I expected for the price. It looks just as nice in person as it does online.

I was worried it might look completely different when it arrived, as you never quite know with online clothing. Thankfully it looks just like the pictures, and the colour is actually even nicer in person. The fit is very flattering without being too tight around the tummy. I’ve already had compliments on it!

I ordered this for a family lunch and was a little worried it wouldn’t arrive in time, but it came much quicker than I expected. Everything was nicely packaged and arrived in perfect condition. The dress itself is lovely and comfortable, and I felt really nicely dressed without feeling overdressed.

I bought this because I wanted something smart but still comfortable, and it really does tick both boxes. I was particularly worried about it clinging around my middle, but it sits beautifully and doesn’t cling at all. I wore it for several hours and was still comfortable by the end of the day.

I had a question about the sizing before ordering and sent a message to customer service. They got back to me quickly and were really helpful, which gave me the confidence to place my order. I’m glad I did because the sizing advice was spot on and the top fits beautifully. It’s nice to have that reassurance when ordering clothes online.

This was actually my second order after being so pleased with my first purchase. I wasn’t sure whether to order another one at first, but I loved the fit of the first top so much that I decided to try this one as well. Once again, the quality and fit are lovely. I’ll definitely be keeping an eye on the new arrivals.

Two Generations, One Eye for Good Clothes

We're Hetty and Harlow — mother and daughter, based in Yorkshire. Years spent buying womenswear for the big high street names taught us what actually works: good fit, fabric that lasts, and pieces you'll still reach for next winter.

So we left to do it our way. No middlemen, no mark-up for the sake of it — just the pieces we'd genuinely pick for you ourselves, sold direct.

Right now, we've a little sale on while we make way for the new season — good pieces, picked as always, just reduced while they last.

Family run, Yorkshire born.
