A Henley in and of itself is perfectly fine men's wear. It's the three-quarter length roll-tab sleeve which raises an eyebrow. The reason is a long-sleeved Henley traditionally has an elasticized cuff. If the sleeve needed to be moved out of the way, it could simply be pushed up. The roll-tab is an unnecessarily fussy detail. In women's wear, a three-quarter length sleeve is appealing because it accentuates the waistline of one's girlish figure and/or hides "bat wings", depending on the age group. Now, granted, the material of this shirt may be jersey knit or some other lightweight material unable to hold a roll of the sleeve on its own... but, again... elasticized cuffs. If a men's shirt is going to have a roll-tab, it is less girly-looking on a more masculine button-down, collared shirt, for example. Fortunately, those shirts are often made of a stiffer cotton which means you can roll up the sleeve on its own without it looking like you are deliberately trying to achieve an hour-glass figure.
