From Atelier scammit:
This jumpsuit has the fun spirit of its designer - the talented Hélène, French blogger of ‘Hélène et les jolis mômes’. Elasticated at the back to accentuate the feminine curves, it can also be pulled in at the front. Two sets of three pleats demark the top of the trousers and follow down to the start of each extra wide legs. The jumpsuit features an invisible zip. It can be made without sleeves, with short sleeves or with a flat or gathered cap sleeve.
