Question about Bridesmaid dress shops

How long do they hold your bm dresses for when they come in?

backstory vent: The owner told me to order the dresses by Beg of February to ensure that they atleast get here by May. Rushing me to get all the girls in everyday & i do. then he calls me & leaves me a voicemail the 2nd week in march that the dresses came in and the girls need to come pick it up W*T*F? So im like ok i tell the girls. No one went to go get it yet cuz they were expecting to pick it up beg of may & get there money straight cuz they have kids and bills. So then he calls me 4 days ago leaving me a voicemail saying they need to get these dresses he has no room for them they need to get it now. Ah hello if your stupid a** hadnt rushed me you wouldnt have the dresses sitting in your store & everyone wouldve picked them up asap. (alot of the girls dont get off work in time by the time he closes so its hard for them to get up there). So 2 are going sat but the others im like you get it when you get it b/c he made this huge scene that if they dont order it by Feb i may not have them in time lol.
