If you're concerned about your refund, please get in touch with your order number and returns tracking number, so we can investigate the delay for you.

A really nice shirt

A really nice shirt - everything looks great when worn - soft fabric, pockets are quite discrete, and - same colour buttons as the fabric ! I love same colour buttons …. as the response on the sizing comment makes - is designed to be worn loose, and this looks better with TWO top buttons undone. That’s loose. And the shirt looks fine like that. I’d buy other colours, but small sizes, all sold as off July 2025. Please, can Isobaa offer more ? The choice of colours is perfect.

Thank you for the great feedback!

There’s no restock planned just yet as this was a new release, but we’ll be reviewing it later this year, and more colours may well be on the cards.

Size: M

Height: 5'7 to 5'9

Fit: Runs large

Recommend: Maybe

Super inconsistent sizing with isobaa

Super inconsistent sizing with isobaa... very disappointing. Difficult being a size S in one item and almost a size L in another, especially when the size guide and fit description are the same across them all

Thank you for your feedback, and we’re sorry to hear the sizing felt inconsistent.

We do try to list detailed garment measurements on every product page to help with fit, especially as some items, like this shirt, are designed with a slightly roomier chest and hem for better airflow and movement in warmer conditions. We'll take your comments on board as we continue to improve clarity across our range.
