Most heavily pregnant women would feel satisfied with their outfit if it earned them a seat on the tube.
But for celebrities, things are a little different.
Mums-to-be want someone to look up to during their pregnancy, and it seems that Beyonce Knowles is the perfect role model.
The singer, actress and fashion designer - who is due to give birth in February - has topped a poll of celebrities most pregnant women respect and whose style they want to copy.
The glamorous star received 35 per cent of the votes, with mums claiming that her down to earth personality and modest way of dressing means they can relate to her more.
Respondents also claimed that they will often buy a magazine or look for Beyonce’s pregnancy outfits online for ideas on how to dress with sophistication and style as their baby bump grows.
Following closely behind Beyonce is Irish beauty and Saturday’s band member Una Healy with 28 per cent.
Mothers think the 30-year-old’s sense of style, and attitude towards her pregnancy, is a shining example for all mums-to-be.
Britain’s Got Talent judge Amanda Holden received 20 per cent of the vote. Mums love her maternity wear and how good she is at looking after her daughter.
Following Amanda, with 14 per cent of the votes, is Jennifer Garner who - with the help of celebrity stylist Rachel Zoe - has kept her pregnancy attire fashionable and effortless.
A spokesperson from fashion retailer Josoblu.co.uk, who commissioned the survey, said: 'Considering Beyonce is one of the most glamorous women in the world and constantly appears in best dressed lists, it is only fitting that she tops the poll for fashionable mums to be.
'Even though this is her first pregnancy it hasn’t stopped Beyonce rocking the highest heels or sparkly numbers – it proves to women that pregnancy can be stylish.
'Ultimately fashion is about individual choice and finding your style and what you feel comfortable in.
'That choice can be limited for mums to be – the key for them is to find some great pieces that they can mix and match – but most of all feel comfortable in as their bump grows.'
