Nothing quite so hilarious as hopping around in T1, trying to get a leg off, trying to stand on the suit and pulling your leg out when everything is cramping up.
However, bodyglide on the tight bits, echo be very careful on the fastening at the back of the neck.
Personally, I hate those stupid rubber swim caps, they are a pain to get on, you look like you are having a facelift, they pull your hair when they come off, or ping off taking your goggles with them. I now use a neoprene swim cap, which is comfortable, warm and slips on and off lovely. If I have to use a silly rubber one, I put it over the top. Downside is you look like a perv.
Let some water in the suit when you get in the water via the neck, it eases the chest off considerably, after the initial shock of it going in, which is bloody freezing and you'll think of us and say, "That bastard just said that to see if I would do it!"
Once you feel comfortable in it, it soon becomes second nature.
