dress question

so i lost almost 15 pounds since i ordered my dress. should i worry about it being too big to be altered? I mean the street clothes i was wearing at the time i bought the dress are now falling off of me. i can still wear them, but i have saggy azz, since my azz doesn't fill it up anymore and the pants ride up cause they're too big on my hips and waist. it just came in yesterday and i'm going to see it on the 21st of april so i guess at the point we'll see how it fits. I ordered a size 14 (at the time i wore a street size 8/10) and the by the time the wedding comes i will probably be a 4/6.
so do guys think the dress store can alter it 2 sizes smaller? (i'll probably need the chest area taken in to a 4 though.) or would i be better off having them get me a dress in a smaller size (if they can, i only have 4 months till the big day)?
the dress has lots of beading on the bodice, and i'm worried that will get ruined if too many alerations are done.

thanks for listening to me ramble!!!

I was told a dress can be takin in 2 sizes. DOn't worry it will be fine. And congrats on the weight loss !!!!!

Congrats on the weight loss

You shouldn't worry about your dress--they'll be able to take it in. They ordinarily tell you that they can take in a dress up to 2 sizes.
