Wales internationals Elise Hughes and Anna Filbey have joined Championship side Crystal Palace, while goalkeeper Poppy Soper has switched to Charlton.
Defender Filbey, 22, and 21-year old forward Hughes, left Charlton in May and join Palace along with 13 other new arrivals signed this summer.
Soper, 20, has joined the Addicks on a two-year deal after departing Women's Super League champions Chelsea.
Palace finished fourth, with Charlton fifth, in the Championship last season.
Soper, who was previously on a dual-registration deal with Plymouth and Chelsea, said she was thrilled to sign her first professional contract.
"I am so happy to be here," she said. "To be part of a Championship club of this standard is a dream.
"This is my first professional contract, I just can't wait to get going. This is all I have ever wanted from a young age to say I am a professional footballer."
Hughes, who previously played for Everton, has made 15 Wales appearances, with former Spurs and Arsenal defender Filbey representing her country on six occasions.
