Is it crazy? (Reem Acra's $4350 Wedding Gown)

I just visited TWO Bridal shops and i just found this
wonderful Reem Acra wedding gown.
It's simple, yet very elegant princess line dress.
it was originally cost about $4500 and
now it's on sample sale for $959.

Every thing about this dress is just so wonderful...
except one thing.

It is SAMPLE.
so which means it got some stains and i've to get an
alteration.

The dress shops 'suggesting' alteration fee is $350.
and also there's another fee for dry cleaning.

So all 'this' and 'that' fees add up for about $550.

Should I go ahead and get this or
Should I wait and get an another decent gown for this price($1550)?
