I assume everyone is as fussy as me so I’d never advocate giving a swimming costume. Knowing an approximate size is not enough; what’s the betting they’ll prefer a specific kind of back, leg cut, colour, make or combination of those things? Same with goggles – I know what I like. And there are other bits of swimming kit that will never scream “GIVE ME”. Buying someone nose clips or mouldable ear wax is like buying a woman Tampax. It’s not a sign that you’re intuitive and resourceful and have been taking careful notes, it’s a sign you forgot and went to the late-night chemist.
