FB Messenger Message Template
<p>How can I achieve this template in fb messenger platform? 
<a href="https://i.stack.imgur.com/7ZLvk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7ZLvk.png" alt="enter image description here"></a></p>

<p>It seems that the color of the shirt and the price are both subtitles of the message but there can only be 1 subtitle in a message. So how can achieve where there are two subtitles?</p>

<p>This is my current message tempalate</p>
