We recommend these TKEES Millie Flat Sandals for your early pregnancy and potentially into your second trimester. The flat design and rubber sole provide excellent stability and traction, which is crucial as your balance shifts. The square toe offers ample room, preventing any constriction as your feet may begin to swell. The minimalist design ensures these sandals don't signal 'maternity wear' and are versatile enough to pair with various outfits, making them a chic wardrobe staple. While the thin straps and backstrap might become less ideal for significant swelling in the later stages of pregnancy, or when bending becomes difficult, their overall comfort and stylish simplicity make them a strong contender for your capsule wardrobe.
