Shopping for wedding dresses is both exciting and exhausting.

Between not knowing what style you want, to differing opinions and price tags, sometimes it can seem all too much. And even though you want that fairytale moment, sometimes there can be a few blips in the way. That's why luxury bridal-wear designer Kate Halfpenny, of Halfpenny London, has given her top advice for all brides to be. And it's not what you might think.

So, if you're hitting the bridal shops for the first time, Kate says to always ask this question first: Are alterations included in the price? Kate told Cosmo that most brides won't even think of it until after they have purchased their gown... but then alterations could rack up to be in the hundreds.

Instead, ask right off the bat, and if they're not included in the price, get a quote for any changes and extra cost. The next piece of advice that Kate encourages is to leave plenty of time to choose your dress. "Some designers that are from other counties need at least six months to put your dress into production," she said.

"You also might pay rush fees on dresses ordered less than three months before your wedding. The designer also added: "I’d say to make sure you don’t get forced into buying your wedding dress by overly pushy sales associates. "DO go away and sleep on it if you’re unsure, unless there is a serious time frame issue."
