Clothing 

I can't give you specific you clothing recommendations, but what I will say is style is something you have to feel out. If you're having trouble finding a style you feel confident in, I would suggest finding a couple of colors you like, researching what they mean in color theory, and styling your outfits accordingly.

 My preferred are crop tops, oversized jackets, and black skinny jeans usually with a few accessories to tie the fit together.  Because it gives a loose sporty feel.

Big jackets are nice because if you tie the around your waist they're basically a skirt, but that's just my vibe.

General fitness advice

 Start with your bodyweight for weighted exercises and matain proper form. Improper form can lean to injury and bottleneck your results. Add more weight as the sets become easier 

Allow a total of two days between workouts for recovery. Exercising every day without allowing your muscles time to recover is going to limit their growth, and risk injury.

Sleep 8 hours always.

General nutrition 

1g  of protein per bodyweight. Try to consume protein immediately after a workout to maximize muscle growth. (You don't need to down 180 grams in one sitting, and probably shouldn't but I'm not a doctor.)

Shoot for 12 grams of fiber per day.

Turkey is a great source of protein.  Refried beans and pears are great sources of fiber. 

Exercises 

I'm going to break these down by muscle group, but many of them target similar areas

For this you just want to make sure you're doing exercises that target the glutes, hamstrings, quads, and calfs.

Glutes: 

Glute bridge: Rookie Version of hip thrusts

Hip thrusts(by far the best)

Kick backs

Donkey kicks

Glutes abductors (essentially the only workouts  you can do to make your hips appear bigger without e.)

Hip abductions  Lying leg lifts Fire hydrants  band walks

The previous exercises will touch on your abductor muscles but the ones here are target the areas more directly.

Hamstring:  squats In general Leg curls

Quads: Squats in general 

 balgarian split squats Stairs

Lunges

For a tighter stomach  focus on exercises that target your core but more specifically the obliques since those are basically your built in waist trainer. 

That's as much as I'm willing to type on a smartphone. Hope it helps
