Then the skin was not properly coded, if it is not showing the style chooser.

I would compare the footer templates in the styles, you should see the following code.

        <vb:if condition="$show['quickchooser']">
            <select name="styleid" onchange="switch_id(this, 'style')">
                <optgroup label="{vb:rawphrase quick_style_chooser}"><option class="hidden"></option></optgroup>
                <vb:if condition="$quickchooserbits1">
                    <vb:if condition="$quickchooserbits2">
                    <optgroup label="&nbsp;{vb:rawphrase standard_styles}">
                    </vb:if>                
                    {vb:raw quickchooserbits1}
                    <vb:if condition="$quickchooserbits2">
                    </optgroup>
                    </vb:if>                    
                </vb:if>
                <vb:if condition="$quickchooserbits2">
                    <vb:if condition="$quickchooserbits1">
                    <optgroup label="&nbsp;{vb:rawphrase mobile_styles}">
                    </vb:if>
                    {vb:raw quickchooserbits2}
                    <vb:if condition="$quickchooserbits1">
                    </optgroup>
                    </vb:if>                    
                </vb:if>
            </select>    
        </vb:if>
