I love the Sarah Reversible Button Tank so much that I got it in two different colors! It’s incredibly functional and perfectly designed for nursing

Wine is a Winner

I already fell in love with the cutting and material for this Sarah and Leah set. Then they made it in this gorgeous deep purple/red colour. Just take my money already.

Perfect fit

This Sarah Reversible Tank fits beautifully—snug but stretchy, and super comfortable all day, especially in Singapore super hot weather. The fabric feels soft and breathable, and it stays in place without clinging. Perfect for layering or wearing solo!

Satisfying Sarah!

The Sarah reversible button tank is really comfortable and true to picture! It’s just that the button at the middle looks considerably darker under all kinds of light for the piece I got, which makes it look off. Love this piece though, I’m already considering getting in another color!

Quality clothes and good customer service

Loved the pieces I got during the Boutique fair. Came home and realized that one of the pieces was in the wrong size ordered and contacted OB immediately. They were very prompt in following up and even offered to exchange the right size along with pickup at my home. Can’t ask for more really. Will definitely look out for their new collections.
