Not disagreeig, but for clarifiction - the suit should be snug but not tight. If it's too tight, especially around your arms that will be a detriment to comfort, warmth, endurance, and safety. If it's too loose the suit will get flushed too easily to provide the optimum insulation value. You can learn more from this website http://www.wetsuitwearhouse.com/
The better quality new suits have super stretch neoprene (IMO well worht a few extra dollars for this) and are actually very comfortable in comparison to the older neoprene materials that could be very stiff and restrictive. Also very important about fitting - size charts can be inaccurate and certain body shapes can add to the challenge of getting a proper fit, so do your due diligence when getting a suit. You can also get a custom suit for not that much more $ if you have trouble fitting into "average" size categories.
