Love this shirt!

The Sage Harbor shirt is now one of my new favorites. I love the detailing on the shirt front. It’s easy fitting and does not wrinkle. Great design!

Hint of whimsy

Love the shape, roomy fit, and the super soft cotton, along with the clever double pocket.

My new favorite shirt

I LOVE the cut of this button down. Drapes so wonderfully and the sleeves hit just right on my wrist. It’s like roomy and fitted at the same time?!? Im not sure how to describe the awesomeness of the cut.

Material is heavier and incredibly soft. It’s one of those shirts that will just get better with every wash/wear. Also looks dang cute

Love, love, love

The denim is structured, yet soft. I love the buttons, the wavy part around the buttons and how the back is longer than the front.

Restores Your Faith in Clothes

The craftsmanship of this shirt is so stunning that it deserves all five stars. The stitching is flawless… tight, clean, and without a single loose thread. The details are precious: the flower buttons, the double pocket, the two-toned contrasting thread, the dual hem, and so much more. I love it. This is how clothing should be made. Fast fashion has lowered the bar across the industry, so I’m grateful to HarperSage for raising it and staying true to their values. I have pieces from HS that have lasted for years, and I’ll continue to support this brand. <3

Delightful details!

This shirt has exceeded my expectations. It is very well made, the details are really stunning from the wavy front closure, the sleeves, the buttons. It is very versatile and goes with everything. I like my tops to be baggy so went for the L, even though the M fit as well. I’ll definitely go back to get a different color.

So many compiments!

Without a doubt I always get stopped by strangers with this shirt and send them to HarperSage! This is such a unique piece and the quality is outstanding. I stayed true to size with a Medium, and it is not that oversized bc of the dolman sleeve- it is so flattering when I style with it my denim- I can't wait to wear this all the way into the Fall!

Was this shirt designed specifically for me? Honestly the quality and detail put into this piece made it feel like a tailored item. Every time I wear this shirt I find a new detail to love. It’s made of a nice material that is both substantial but with a lovely drape. Will absolutely be making another purchase!

Best Shirt EVER!

I've worn this top twice - and got soooo many compliments! Love the fit, color and precious buttons!
