Beautiful dress (finally!) but she’s too old to be going strapless. To look good in a strapless dress, certain aspects of one’s body still need to be young and (ahem!) perky, PLUS you need serious boning in the dress or, preferably, a serious undergarment that really pushes everything upward. Looks like she has relied on the less successful expedient of just making the dress very tight across the boobs. Certainly, that will hold up the dress, but it doesn’t look good. She STILL needs a good wardrobe consultant!
She can go strapless..she’s got the arms....
