Short Fashion Buying Guide
Choosing the Correct Size
- Size up rather than down if you’re between sizes, especially in maternity-specific pieces meant to stretch over a growing belly.
- Check the brand’s maternity size chart specifically, since maternity sizing can run differently than a brand’s regular size chart.
- Read reviews mentioning trimester and belly size when available, since fit can vary a lot depending on how far along a reviewer was.
What to Consider for Fall Maternity Outfits
- Stretch and adjustability matter more than usual. Look for ruched sides, wrap styles, or adjustable waistbands that can grow with you.
- Layers solve a lot of temperature problems. Your body temperature can run warmer during pregnancy, so easy-to-remove layers help.
- Soft, breathable fabrics reduce discomfort. Skin can be more sensitive during pregnancy, so avoid anything stiff or scratchy.
- Don’t be afraid to size up in non-maternity pieces too. An oversized sweater or cardigan from the regular section often works beautifully over a bump.

- Keep a cardigan or jacket within reach. Pregnancy can affect body temperature regulation, so easy layers matter even more than usual.
