Since her last bikini had a skirted bottom, I asked whether she wanted a skirt again or not. And of course she still wanted a skirt on her bikini. The pattern didn’t include a skirt so I just added a rectangular piece of lycra, twice the width of the waist and gathered this. Then I attached the skirt to the bottom before attaching the waist band. The skirt ends halfway the bottom of the bikini. I didn’t finish the edge of the skirt. 
Our girl is in between sizes and I decided to size up. For the next swimsuit I would size down (mainly for the top), it would be little bit tighter, which is what a swimsuit needs. I am also thinking of adding some swim elastic to the bottom of the top. It is included in this bikini and this swim top. Our girl loves to jump, dive and is very active in the water. Her swim top moves up slightly when she jumps in so a little bit of swim elastic would prevent that. Luckily it can easily be added afterwards.
