We’ve been getting some great questions from people visiting our online store. We thought we’d share this visitor’s question and our response since we think others (maybe even you) may be wondering the same thing.
(btw: we’ll try to get some more pictures up to show how our undershirts look under some collared shirts — thanks for the suggestion)

I found your shirts on some car blog when I did a search for best undershirts. ribbedtee: that’s great to hear! we agree that we have the “best undershirts” 
To get a snug fit I’ve been buying size small and even those seem to be getting bigger every year. I used to buy medium.
What size is the guy in the v neck putting on the shirt in the pictures wearing? I’m probably his size.
I’m deciding between v and crew. It looks like the V is fairly high and the crew is low so in the end neither shirt is very visible under a collar but might peek out a bit. It would be helpful if you added some pictures of the undershirts on the models under various types of collared shirts so I could see how the crew or V style looks.

Thank you for your interest in RibbedTee undershirts. The “guy in the v neck putting on the shirt” on the website is actually wearing a size large, however, as you can see, it fits a little big. I am confident a size medium would fit you perfectly. The reason for the v neck looking high around the neck is due to the undershirt rising a bit as he is reaching back to put on the collared shirt. If you will see in other photos, the v neck is perfectly designed to wear underneath a collared shirt without being noticed.
I hope this answers your inquiry. Please let us know if you have any further questions. We look forward to having you as a very satisfied customer.
