☀️ 1. Summer Dress Styles: What’s Out There?

Understanding the core categories of summer dresses helps narrow down your wardrobe:

▪️ A-line Dress

Fitted at the top, flared at the hem.
Flatters pear and hourglass shapes.
Works in cotton, viscose, or linen.

▪️ Wrap Dress

Ties at the waist, with an adjustable V-neck.
Ideal for curvy, busty, or petite women.
Creates balance for broad shoulders or narrow hips.

▪️ Shirt Dress

Structured with a button-down front.
Versatile, office-friendly, great for rectangle shapes.
Pair chambray, cotton, or linen blends for breathability.

▪️ Tiered Midi / Maxi

Relaxed fit with volume.
Best for apple shapes and anyone who prefers waist-skimming comfort.
Ideal in cotton or crinkled viscose for movement.

▪️ Slip Dress

Bias-cut, minimal seams, often satin or viscose.
Flattering on lean frames or hourglass shapes.
Layers easily with knits or jackets.

👗 2. How to Shop for Your Body Shape

Finding the right dress is about balancing proportions:

🧍‍♀️ Hourglass

Emphasise the waist. Look for wrap, belted, or fit-and-flare styles.
Avoid shapeless dresses that hide your natural curves.

🧍 Pear

Balance wider hips with structured shoulders or flared skirts.
Shirt dresses and A-line midis work well.

🧍‍♂️ Apple

Focus on empire waists or shift dresses that skim the tummy.
Avoid tight waistlines and bodycon styles.

🧍‍♀️ Rectangle

Add definition with ruffles, belts, or asymmetric hems.
Tiered or puff sleeve dresses can create curves.

🧍 Petite

Choose shorter hemlines or high-waisted silhouettes.
Avoid overly long or voluminous styles that can overwhelm.

🧍 Tall

Maxi dresses and mid-calf styles flatter long frames.
Look for adjustable straps and longer cuts that accommodate height.
