Changement au niveau de la taille
J’ai commandé la même grandeur (S) que toutes mes autres brassières de la même marque et j’en au même une du même modèle acheté l’an dernier et celle reçu a 2 po de moins autour du torse, c’est beaucoup trop serré. Les deux nouvelles bralettes commandées de cette marque sont arrivées beaucoup plus petites que celles que j’ai déjà… la qualité ne semblait pas aussi belle.
