Primrose Button Detail Maxi Dress

Primrose button butterfly dress

I love this dress except I will have to wear it with a bolero as my chest is too large for the skimpy bust snd spaghetti straps. If I can’t find something to match might need to return it. How much longer is it returnable? I will greatly regret this as the material is exquisite and the customer service over returning snd sending a bigger size excellent. One fault if thst it puckers on the hips.
