adding bootstrap class attributes to editorformodel ASP.net MVC

Question

is it possible to add bootstrap class attributes to EditorForModel? The model generates 4 fields but they are not properly aligned. I was trying to add form-control class but it add the attribute in each field.

This is how I added the Form:

 @using (Html.BeginForm())
    {
        <fieldset>
            @Html.AntiForgeryToken()
            <legend>@ViewBag.Title</legend>
            @Html.EditorForModel(new { htmlAttributes = new { @class = "form-control" }})
            <p><input type="submit" value="Save" /></p>
        </fieldset>

    }

add this is whats in the page-source

 <form action="/Products/Edit/1" method="post">    
    <fieldset>
            <input name="__RequestVerificationToken" type="hidden" value="eIwHZW5P2wPCTWgcqYe9SH2Ad_rKuYNWgvvplsqxo7vYLGXzaXlVKR5pPrjVsag7lRmUsm1M-r3sZYDQyThLL_1o1PQUKnKgbCuI88NwQMQ1" />
            <legend>Edit</legend>
            <input class="form-control" data-val="true" data-val-number="The field ProductID must be a number." data-val-required="The ProductID field is required." id="ProductID" name="ProductID" type="hidden" value="1" /><div class="editor-label"><label for="ProductName">Product Name</label></div>
    <div class="editor-field"><input class="form-control text-box single-line" data-val="true" data-val-required="Product name is required." id="ProductName" name="ProductName" type="text" value="chai" /> <span class="field-validation-valid" data-valmsg-for="ProductName" data-valmsg-replace="true"></span></div>
