The Knotty Frenchies tutus are made over two layers (classic) or three layers (de luxe) of tulle on a lovely crochet elastic waistand for more comfort and flexibility for your pup, and finished with a lovely satin ribbon to adjust and have a perfect fit.Below the belly there is a gap where there is no tulle to give your pup more freedom of movements. How to order ? Please refer to the sizing guide and then select the suitable size in the dropdown list. if your pup is in between two sizes, i recommend selecting the smallest size because the tutus are made on crochet elastic waistband. When proceeding to the checkout, please provide in the "add notes" your chosen colours and your pup exact belly measurements. The measurements must be taken below the ribs cage.
